OTDM add-drop multiplexer based on time-frequency signal processing

, 2006
A time-division add-drop multiplexer capable of high-extinction-ratio operation is presented both theoretically and experimentally. The approach used is based on time-to-frequency domain conversion of optical signals and relies upon the switching of ...

Universal Optical Frequency Comb

, 2010
We demonstrate that whispering gallery mode resonators can be utilized to generate optical frequency combs based on four wave mixing process at virtually any frequency that lies in the transparency window of the resonator host material. We show theoretically how the morphology of the resonator can be engineered to produce a family of spectrally ...

Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits

Laser &Photonics Reviews, EarlyView.
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...
