Traditional lock-in detection methods have been limited for wide-field imaging. Here, the authors present an all-optical design which enables four quadrature image channels to be recorded simultaneously, and show demodulation of wide-field images bas

Optoelectronic oscillators (OEO) have become of paramount importance for the generation of high spectral purity, (optically-carried) microwave signals. The most widespread architecture uses a Mach-Zehnder Modulator as the generator of the RF modulati

Similar to vertical-external-cavity surface-emitting lasers (VECSELs) [1] , MECSELs [2] are high beam quality light sources with typical M 2 values close to an ideal Gaussian beam. The difference is the absence of the mono-lithically integrated distr
