Abstract

Electrically controlled phase shifter and optically controlled modulator have been developed and manufactured on basis of dielectric image guides (DIGs) in 37 to 120 GHz frequency band. Phase shift is possible in the 360 degree range, with 2 degree accuracy, while direct losses are approximately 1.5 dB. Modulator is narrowband, approximately 300 MHz, with 25 B modulation depth, and approximately 10^-5 sec time constant.
