Protein-Semiconductor Integrated Photoreceivers
Abstract
Bacteriorhodopsin (bR) is a light harvesting protein in the purple membrane of microorganism called Hallobacterium Salunarum. Its high internal resistance and very small current have limited the possible applications with semiconductors. One possible solution is to apply bR with field effect transistors (FETs) for FETs' high input resistance. We have demonstrated monolithically integrated bR-semiconductor transimpedance amplifer polarization sensitive photoreceivers and phototransceivers with light emitting lasers of the 655nm peak wavelength. The transient nature of the bio-transceiver output is observed to be similar to that of intrinsic bR photoelectric response.
