Selfhomodyne Photonic Microwave Receiver Architecture Based on Linear Optical Modulation and Filtering
نویسندگان
چکیده
We present a self-homodyne photonic microwave receiver architecture that uses linear optical modulation and optical filtering for data down-conversion from a microwave carrier. Preliminary results demonstrate the feasibility of this technique for demodulating up to 100 Mb/s digital data from carrier frequencies above 10 GHz. © 2007 Wiley Periodicals, Inc.

متن کاملA photonic chip based frequency discriminator for a high performance microwave photonic link.
We report a high performance phase modulation direct detection microwave photonic link employing a photonic chip as a frequency discriminator. The photonic chip consists of five optical ring resonators (ORRs) which are fully programmable using thermo-optical tuning. In this discriminator a drop-port response of an ORR is cascaded with a through response of another ORR to yield a linear phase mo...
متن کاملOptical Filter Based On Point Defects in 2D Photonic Crystal Structur
In this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. In designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. The initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...
