Abstract
This paper describes two types of waveguide modulators designed for CO2 laser frequency shifting applications. The first one is a low optical loss ThF4 buffered GaAs waveguide, interfaced with a broadband microwave transmission line operating in the X- and Ku-band (8-18 GHz). The second one is a GaAs single mode waveguide modulator operating in the baseband (0-5 GHz). Device structures and performance will be detailed.
