Design of chirped grating lenses on optical waveguides for opto-electronic signal processing is presented in this report. Fundamental limitations of the performance of chirped grating lenses due to material properties, fabrication tolerance and design parameters are discussed. In addition electro-absorption and electro-refraction properties in GaAs and InP semiconductors are presented. Cross modulation of optical radiations at two different wavelengths has been observed in GaAs. It has the potential of exhibiting optical AND logic. Keywords include Chirped grating waveguide lens opto-electronic signal processing and electrorefraction III-V compound opto-electronic devices.
