Patent ID: 8830450

Claim:
A combination photonic detection and identification system comprising: a photonic membrane with through pores, the through pores having inner walls to which chemical or biological target specific anchors are adapted to be attached; a first optical input to the photonic membrane, the first optical input in-plane with the photonic membrane; a first optical output detecting arrangement arranged in-plane with the photonic membrane; a second optical input to the photonic membrane, the second optical input arranged out-of-plane to the photonic membrane; and a second optical output detecting arrangement arranged out-of-plane to the photonic membrane, wherein the photonic membrane is a silicon photonic crystal further comprising a SERS substrate comprising a surface coated with metal rings facing the second optical input and the second optical output detecting arrangement, the SERS substrate being tuned to excite plasmons, wherein the SERS substrate is adapted to couple the second optical input into molecules at or near a surface of the SERS substrate, the coupled second optical input from the molecules releasing photons, and wherein the metal rings are in correspondence of entrances of the through pores, and wherein the through pores are distributed on the photonic membrane along multiple regions of through pores, wherein through pores pertaining to one region have inner walls to which one type of chemical or biological target specific anchor is attached, and wherein through pores pertaining to another region have inner walls to which another type of chemical or biological target specific anchor is attached.
