Abstract
A millimeter-wave optically injection-locked oscillator has been designed and fabricated. It represents the first millimeter-wave hybrid transistor oscillator locked to a long-wavelength optical signal. The oscillator could be used as a photoreceiver in remote base stations in future picocellular communication systems employing fiber-optic backbones; its high "gain" (output relative to input locking signal) and relative flatness in output power may make it attractive compared to simple millimeter-wave amplifier configurations. Measurement results show the output signal exhibits little variation (less than 0.7 dB) with input optical power changes of 6 dB. A locking bandwidth of 2.6 MHz has also been achieved.
期刊介绍：
The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
