We present an InGaAs/InP single-photon avalanche diode (SPAD) with $10 \mu \mathrm{m}$ -diameter active area, designed for fiber-based quantum applications. Improved design and fabrication lead to low dark count rate (1000 cps at 225 K), 25% photon d

We experimentally investigate the smallest germanium waveguide cavity resonators on silicon that can be designed to work around 1.55 mu m wavelength and observe an almost 30-fold enhancement in the collected spontaneous emission per unit volume when

We present a new compact system for time-domain diffuse optical spectroscopy of highly scattering media operating in the wavelength range from 1100 nm to 1700 nm. So far, this technique has been exploited mostly up to 1100 nm: we extended the spectra

Recently there has been considerable effort to develop photon-counting detectors for the near-infrared wavelength range (up to 1700 nm). However, a practical detector, which can be employed in many real applications and has both high count rates and
