Novel High Resolution Detector for X-Ray CT and DR

Not Available A new approach to significantly increasing the level of monolithic integration of InP based photonic integrated circuits for RF applications is the subject of this proposed Phase I program. The method is based on a vertically coupled twin wave guide design that has already been successfully used to fabricate lasers and amplifiers. The fabrication process requires no epitaxial re-growth, resulting in high product yields. We propose to further develop this technology and use it to fabricate photonics integrated circuits (PICs) consisting of single frequency laser diodes, high frequency external modulators, wave guides, and mode transformers. Successful demonstration of such circuits will make it possible to fabricate PICs consisting of arrays of such laser/modulatros and semiconductors optical amplifiers, thus further demonstrating the value of this technology for applications such as photonic phased array antennas, is hampered by the extreme complexity and high component count required. Increasing the level of component integration, can significantly lower the cost of such systems and accelerate their acceptance into the commercial and military markets.
