Microwave Photonics Laboratory

About us

The main laboratory research and development activity belongs to the microwave photonics, which study interactions between microwave and optical waves for the generation, transmission and processing of microwave signals. Microwave photonics allows to create microwave devices and systems with outstanding parameters, which cannot be achieved by traditional electronic techniques. Main advantages of microwave photonic devices and systems are connected with unique properties of optical fiber:
– ultra-low loss (less than 0.0005 dB/m)
– ultra-wide band (tens of gigahertz)
– high immunity to electromagnetic interference
– full galvanic isolation
– low mass and size

Laboratory research and development fields
– high-power photodiode modules with bandwidth up to 100 GHz for the spectral range of 1.2-1.7 μm
– fiber-optic links and systems for transmission and distribution of microwave signals with bandwidth up to 100 GHz
– photonic generation, analysis and processing of microwave signals with bandwidth up to 100 GHz
– ultralow-phase-noise optoelectronic oscillators in the frequency range from 8 to 100 GHz

Applications of microwave photonic devices and systems
– radars
– wireless communications
– microwave measurements
