High sensitivity 40 Gbit/s preamplified SOA-PIN/TIA receiver module for high speed PON

Abstract

We demonstrate a receiver module which associates a preamplified detector with a transimpedance amplifier for next generation PON network. The module achieved in NRZ a very high sensitivity of -23 dBm at 25 Gbit/s and -21 dBm at 40 Gbit/s.

High-speed photodetectors in optical communication system

“…Therefore, many researchers have provoked considerable efforts to improve the sensitivity performance of PDs. In 2012, Nada et al reported that an APD together with a commercially available transimpedance amplifier (TIA) realized −21.7 dBm sensitivity at a data rate of 25.8 Gb/s which was assembled in the ROSA [48] . However, commercial APD above 10 Gb/s is scarcely available, and because of the low ionization coefficients ratio of the avalanche material, it is leading Ref.…”

“…This photoreceiver operates with 3 dB bandwidth up to 110 GHz and a dark current of 1 nA at 1.55 mm wavelength [50] . From 2012 to 2015, an integrated SOA-PIN photonic circuit with a high responsivity of 88 A/W and a large −3 dB bandwidth of 50 GHz [51] , a receiver with an integrated SOA-PIN chip and a TIA with a broad bandwidth of 35 GHz and a very high sensitivity of −23 dBm at 25 Gb/s and −21 dBm at 40 Gb/s [52,53] is achieved in succession by the Caillaud group shown in Fig. 1.…”

InP-based high-speed monolithic PIN photodetector integrated with an MQW semiconductor optical amplifier

“…For example, to improve the gain and saturation output power, Raring et al 12) used quantum well mixing 13) and more than four metal-organic chemical vapor deposition (MOCVD) steps to achieve high-and low-optical-confinement SOAs on the same chip. Moreover, in order to improve the coupling efficiency of the SOA and fiber waveguide, III-V lab [4][5][6][7][14][15][16][17][18] employed electron beam lithography and up to three growth steps. Consequently, an approach that requires fewer growth steps is a simpler process and allows for the independent design of the SOA and PD.…”
