Optoelectronic oscillator controlled by photodiode-based optoelectronic chromatic dispersion and FBG integration

Abstract

High Optoelectronic Chromatic Dispersion in Ge PN-type photodetectors affects the output of the Optoelectronic Oscillator. This is utilized to achieve high sensitivity wavelength monitoring and strain sensing. The sensitivity is enhanced for higher oscillating mode numbers and lower cavity lengths.
