Abstract
We report the first realization of low-loss orientation-patterned gallium antimonide waveguides for frequency conversion in the mid-infrared. Planar waveguide structures were grown by molecular-beam epitaxy on periodically patterned gallium arsenide templates prepared by wafer bonding. Ridge waveguides were designed and fabricated from the planar structures. Record losses of 0.73 dB/cm in periodically oriented waveguides were measured at 2 μm.
