Concepts

TL;DR

We have developed 10, 20, 30, and 40 Gb bandwidth balanced photoreceivers for both analog and digital fiber‑optic communications. The receivers operate over C and L bands as well as 1064 nm and 1310 nm, enabling low‑noise RF photonic links and high‑speed 10 Gb/40 Gb DPSK and DQPSK modulation formats. Balanced photoreceivers deliver RIN noise cancellation, even‑order harmonic suppression, doubled optical power handling, and improved reliability.

Abstract

We have developed 10, 20, 30, and 40 Gb bandwidth balanced photoreceivers which have applications for both analog and digital fiber optic communications. The devices can operate at C and L optical bands as well as 1064 nm and 1310 nm wavelengths. The analog applications include low noise RF photonic links. The digital applications include 10 Gb and 40 Gb DPSK and DQPSK modulation formats for enhanced sensitivities. The advantages of balanced photoreceivers are: RIN noise cancellation, suppression of even order harmonics, doubling the optical power handling capacity of a photonic link, and better reliability.
