Whispering gallery mode (WGM) resonators are axially symmetric dielectric structures ranging in size from tens of microns to a few mm, and can trap light in a small volume. The modes are solutions of Maxwell’s equation and represent waves that propagate close to the surface of the resonator structures, along the perimeter.
OEwaves' homodyne based system is unique in wideband measurement without requiring other reference laser source. The complete system operates with ease, speed and precision, and a simple graphic user interface via a PC, without requiring any additional test equipment
OEwaves developed an Ultra-Narrow Linewidth Laser Source based on the self-injection locking of a semiconductor laser diode to our proprietary high quality factor (Q) Whispering Gallery Mode (WGM) optical micro-resonator to achieve robust super-narrow instantaneous spectral linewidth as low as < 1 Hz.
OEwaves’ patented opto-electronic oscillator (OEO) is based on an approach that is fundamentally distinct from conventional electronic oscillators. These innovative oscillators produce highly spectrally pure microwave and mm-wave signals using an opto-electronic feedback loop.
