0412387BhattacharyaThis proposal is concerned with the study of the basic photoresponse characteristics of the light-sensitive protein bacteriorhodopsin (BR) and its application to novel light switches and modulators using semiconductor-based photonic crystals. Genetic engineering and chemical modification of BR will be studied, to reduce the fall time in the protein photoresponse. The protein will be deposited on selected surfaces by electrophoretic deposition and other techniques. The response times, of ~ picoseconds, will be measured by a novel terahertz radiation detection scheme. BR-FET-VCSEL monolithically integrated bio-photoreceivers and phototransceiver arrays will be designed, fabricated and characterized. Utilizing the large electro-optic effect in BR, its application to novel all-optical light switches in semiconductor photonic crystals will be demonstrated.

该提案涉及光敏蛋白质细菌视紫红质（BR）的基本光响应特性的研究及其在使用基于光子晶体的光开关和调制器的新型光开关和调制器中的应用。将研究BR的基因工程和化学修饰，以减少蛋白质光响应的下降时间。蛋白质将通过电泳沉积和其他技术沉积在选定的表面上。 采用一种新颖的太赫兹辐射探测方案测量了~皮秒的响应时间。 BR-FET-VCSEL单片集成生物光接收器和光收发器阵列将被设计，制造和表征。 利用BR的巨大电光效应，将其应用于新型的半导体光子晶体全光开关。
