Abstract

An high-efficiency optical filter composed of counter-propagating wavelength converter in ZnTe, is demonstrated. The device has a extremely narrow bandwidth 0.5 angstrom, corresponding to pump intensity 1.2MW/cm² and length of crystal 1cm, is tunable over several nanometers in bandwidth using combination of length of device and pump intensity. The presented scheme is also a candidate of wavelength-dependant switcher.
