摘要： A method, system, and apparatus are disclosed for a ruggedized photonic crystal (PC) sensor packaging. In particular, the present disclosure teaches a ruggedized packaging for a photonic crystal sensor that includes of a hermetic-seal high-temperature jacket and a ferrule that eliminate the exposure of the optical fiber as well as the critical part of the photonic crystal sensor to harsh environments. The disclosed packaging methods enable photonic crystal based sensors to operate in challenging environments where adverse environmental conditions, such as electromagnetic interference (EMI), corrosive fluids, large temperature variations, and strong mechanical vibrations, currently exclude the use of traditional sensor technologies.

摘要： A data communication system is disclosed including a cable medium and modulator adapted to carry data and power between a high speed data source and a high speed data sink. Relatively high speed data (e.g. the TMDS data of an HDMI interface) may be carried on optical waveguides in the cable medium. Relatively low-speed data (e.g., DDC data and clock, and CEC of an HDMI interface) may be carried on a separate set of optical waveguides or wire mediums. The optical waveguides allow for substantially less signal distortion of the high-speed data, thereby allowing the cable medium to achieve much higher lengths without significantly affecting the high-speed signaling.
