Microwave Photonic Harmonic Down-Conversion Based on Cascaded Four-Wave Mixing in a Semiconductor Optical Amplifier
Published 2018-01-01Get full textA reconfigurable and wideband photonic method is proposed for microwave photonic harmonic down-conversion based on cascaded four-wave mixing in a semiconductor optical amplifier (SOA). The cascaded four-wave mixing in SOA triggers high-order harmonics generation of local oscillator (LO) in the optic...

Wideband and High-Resolution Measurement of Magnitude-Frequency Response for Optical Filters Based on Fixed-Low-Frequency Heterodyne Detection
Published 2017-01-01Get full textA high-resolution electrical method is proposed for magnitude-frequency response measurement of optical filters based on fixed-low-frequency heterodyne detection. The method consists of an acousto-optic frequency shifter and two phase modulators located in a Mach–Zehnder interferometer ar...
