We propose a simple integrated narrowband filter consisting of two grooves on the surface of a slab waveguide. Spectral ......

Stable dual-mode semiconductor lasers can be applied for the photonic generation of microwave and terahertz waves. In th......

Relative intensity noise (RIN) and high-speed modulation characteristics are investigated for an AlGaInAs/InP hybrid squ......

A low-cost light-emitting diode (LED) is sufficient to pump a quasi-continuous-wave bidirectional high-Q whispering-gall......
