2High-performance waveguide-integrated germanium PIN photodiodes for optical communication applications[Invited]显示文摘This paper reports on high-performance waveguide-integrated germanium photodiodes for optical communications applications.200 mm wafers and production tools were used to fabricate the devices.Yields over 97%were obtained for three different compact photodiodes(10×10μm and intrinsic region width of 0.5,0.7,and 1μm)within the same batch of three wafers.Those photodiodes exhibit low dark currents under reverse bias with median values of 74,62,and 61 nA for intrinsic widths of 0.5,0.7,and 1μm,respectively,over a full wafer.Responsivities up to 0.78 A∕W at 1550 nm and zero bias were measured.Zero bias operation is possible for 25 and 40 Gbps with receiver sensitivity estimated to−13.9 and−12.3 dBm,respectively.Léopold Virot Laurent Vivien Jean-Marc Fédéli Yann Bogumilowicz Jean-Michel Hartmann Frédéric Bœuf Paul Crozat Delphine Marris-Morini Eric Cassan 2013Photonics Research2013,1,3:2
325 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN 2019Photonics Research2019,7,4:2
