A 70-GHz bandwidth commercial photodiode has been coupled to W-band waveguide and used as a photomixing source from 75 to 170 GHz. Maximum power conversion efficiency of 1.8% was obtained at 75 GHz, where an optical input of +10 dBm yielded a nonsatu

Millimeter-wave generation by photomixing at 1.55 /spl mu/m in long-wavelength velocity-matched distributed photodetector (VMDP) is experimentally demonstrated. The VMDP exhibits a dc responsivity of 0.25 A/W, a breakdown voltage of 7-9 V, and up to

The temporal drift due to the polarization noise in an ultralow temporal drift photonic phase reference distribution system is analyzed. The temporal drift is shown to be associated with the polarization changes, the differential group delay of the s

Generation of 2 THz Span Optical Comb in a Tunable Fiber Ring Based Optical Frequency Comb Generator
Publikováno v:
IEEE International Topical Meeting on Microwave Photonics, MWP 2007
The generation of a 2 THz span optical comb, defined within a 10 dB power envelope and consisting of 200 optical comb lines, all stronger than -20 dBm without amplification, is reported. The effective transmittance of the generator is 11.5 dB. The co

Methods for the photonic generation of stable millimetre-wave reference signals are examined and compared. In particular, the generation of optical comb lines with microwave frequency separation in an amplified fibre ring and by sideband generation w

A monolithic IMPATT (impact avalanche transit time) oscillator operating in the 50-GHz region has been controlled in frequency in an open microwave resonator. The noise spectrum of the oscillator in a closed quasi-optical cavity showed substantial im
