Since about two decades optical detectors have been integrated to- gether with electronics in optoelectronic integrated circuits or photodiode ICs.

This evolution towards silicon-based technolo- gies is based on the existing mature (Bi)CMOS manufacturing. Absfruct-Advantages attributed to the MSM detector in- clude its low capacitance, high-speed and compatibility with. This has resulted in many demonstrations of OEIC receivers, both in GaAS and InP. Detection occurs when an infrared photon of sufficient energy kicks an electron from the valence band to the conduction band.

LEDs which are reverse-biased to act as . In this paper, I will review the subjects of optical detectors and optical receivers. I will focus, at times, on the lessons learned while performing my own research and development activities, and on how and . The detector also has the ability to monitor and discard transient sources of smoke. Finely pixelated SiPM arrays have opened new opportunities in PET detector development, such as the utilization of monolithic scintillator crystals. In the present paper we report the first . Nanowire Single-photon detector with an integrated optical cavity and anti- reflection coating.

The Silicon LEDs are avalanche diodes reverse biased beyond the breakdown voltage. In addition to passive optical devices for realizing photonic quantum gates, active elements, such as single-photon sources and single-photon detectors , are essential ingredients for future optical quantum circuits. Material systems that allow for the monolithic integration of all components are particularly . Though the active device structure of the RCE detectors remains close to other conventional photodetectors , the effect of the optical cavity, which allows wavelength selectivity and an enhancement of the optical field due to resonance, allows the photo detectors to be made thinner and therefore faster, while simultaneously . When operating the detectors close to the critical current we achieve high on-chip single photon detection efficiency up to at telecom wavelengths, with uncertainty dictated by the variation of the . However, the monolithic integration of sources, waveguides and detectors on the .
