Chem/Bio Sensing with Non-Classical Light and Integrated Photonics


With evidently emerging advances in practically applicable quantum technology in communications, cryptography, computing, metrology, and lithography, harnessing this technology platform for chem/bio sensing scenarios is a logical consequence. Given the progress in fabrication, miniaturization, and integration of optical and especially of infrared quantum photonics, the combination of efficient single-photon sources, waveguiding/sensing structures serving as active optical transducer and advanced detector materials, increasingly sophisticated on-chip devices enabling ultra-sensitive detection schemes in chem/bio analysis are on the horizon. Besides the intrinsic molecular selectivity and non-destructiveness of near- and mid-infrared sensing schemes, chem/bio sensors taking advantage of non-classical light sources promise sensitivities beyond the standard quantum limit. In the present review, recent achievments towards on-chip chem/bio quantum photonic sensing platforms are discussed along with appropriate recognition chemistries facilitating the detection of relevant (bio)analytes at ultra-trace concentration levels. By combining these developments we propose a testbed for reaching integrated quantum sensing on two fiber coupled GaAs chips together with semiconductor quantum dots as single-photon sources.
