MECSEL: new concept for optically pumped semiconductor disk lasers with versatile wavelength (Conference Presentation)

Read Abstract +

Semiconductor disk lasers, also called vertical external-cavity surface-emitting lasers (VECSELs) have advantageous properties such as high output power, wavelength flexibility due to bandgap engineering and near-diffraction limited beam quality. The possibility to insert intra-cavity elements – filters, frequency doubling crystals or semiconductor saturable absorber mirrors (SESAMs) – enables wavelength tuning, second harmonic generation or mode locking with ultra-short pulses. A major challenge for these laser sources is the removal of heat which is introduced by optical pumping. The thermal management can improved by placing only the active region directly between two heat spreaders. This membrane external-cavity surface-emitting laser (MECSEL) allows emission in an even larger wavelength range, since the growth is not restricted by a distributed Bragg reflector. We present the fabrication, processing and characterization of MECSELs using different material systems for laser emission at various wavelengths in the visible and in the infrared spectral range. Our semiconductor structures are grown by metal-organic vapor-phase epitaxy and contain quantum wells (QWs) or quantum dots (QDs) in the active regions. We discuss our latest results of the membrane laser concept with investigations of strain effects on the photoluminescence and the laser emission and different pumping schemes. In particular, we show results of a MECSEL placed into a linear cavity and pumped by a 532 nm laser. The system was operated at a heat sink temperature of 10°C and achieved nearly 600 mW at 3.7 W pump power. The slope efficiency achieved here was 22.3 % with a threshold pump power of 1 W. This slope efficiency exceeds any slope efficiency published before with green pumped conventional VECSEL in this emission range at these elevated heatsink temperatures. Including a birefringent filter into the laser cavity allows for a tuning of the emission laser wavelength. The group could demonstrate a tuning range of 24 nm (650 nm – 674 nm), which is the highest value achieved in this spectral range by semiconductor lasers to date. All these achievements come with the expected Gaussian TEM00 mode with a beam quality factor of M2< 1.06[Optica 3(12), 1506-1512 (2016)]. To demonstrate the flexibility and usability of the MECSEL approach, we have created an optically pumped laser with a GaInAsP membrane for emission around 1000 nm, together with a group in Dundee. The set-up of the laser was similar to that of the red spectral range but instead of diamond, SiC was used as heat spreader material. Nevertheless, the achieved output powers could exceed 10 W with a slope efficiency of 27.5% and this with the heat spreader on only one side. This work was as well recently published in Electronic Letters 2017 [DOI:10.1049/el.2017.2689]. Actually, we realized a running membrane laser at a wavelength of 608 nm, a wavelength not accessible so far. The characterization measurements are now ongoing, first results will be presented at the conference.

Low-noise quantum frequency down-conversion of indistinguishable photons (Conference Presentation)

Read Abstract +

Single-photon sources based on quantum dots have been shown to exhibit almost ideal properties such as high brightness and purity in terms of clear anti-bunching as well as high two-photon interference visibilities of the emitted photons, making them promising candidates for different quantum information applications such as quantum computing, quantum communication and quantum teleportation. However, as most single-photon sources also quantum dots typically emit light at wavelengths of electronic transitions within the visible or the near infrared range. In order to establish quantum networks with remote building blocks, low-loss single photons at telecom wavelengths are preferable, though. Despite recent progress on emitters of telecom-photons, the most efficient single-photon sources still work at shorter wavelengths. On that matter, quantum frequency down-conversion, being a nonlinear optical process, has been used in recent years to alter the wavelength of single photons to the telecom wavelength range while conserving their nonclassical properties. Characteristics such as lifetime, first-order coherence, anti-bunching and entanglement have been shown to be conserved or even improved due to background suppression during the conversion process, while the conservation of indistinguishability was yet to be shown. Here we present our experimental results on quantum frequency down-conversion of single photons emitted by an InAs/GaAs quantum dot at 903.6 nm following a pulsed excitation of a p-shell exciton at 884 nm. The emitted fluorescence photons are mixed with a strong pump-field at 2155 nm inside a periodically poled lithium niobate ridge waveguide and converted to 1557 nm. Common issues of a large background due to Raman-scattered pump-light photons spectrally overlapping with the converted single photons could largely be avoided, as the pump-wavelength was chosen to be fairly longer than the target wavelength. Additional narrowband spectral filtering at the telecom regime as a result of the small conversion bandwidth and using a high-performance fiber-Bragg-grating solely left the detector dark counts as the only noise source in our setup. Therefore, we could achieve conversion efficiencies of more than 20 %. In order to test the indistinguishability, sequentially emitted photons were fed into a Mach-Zehnder interferometer and spatially as well as temporally overlapped at the output beam splitter. Cross-correlation measurements between both output-ports of the beam splitter exhibit two-photon interference contrasts of more than 40 % prior to and after the down-conversion step. Accordingly, we demonstrate that the process of quantum frequency conversion preserves photon indistinguishability and can be used to establish a versatile source of indistinguishable single photons at the telecom C-Band. Furthermore our scheme allows for converting photons in a wavelength band from 900 nm to 910 nm to the same telecom target wavelength. This enables us to test indistinguishability of frequency-converted photons, originally stemming from different sources with dinstinguishable wavelengths.
