Abstract

Recent advances in short reach 100 Gb/s intensity modulation and directed detection systems are briefly reviewed. As an illustrative example of using digital signal processing enabled transmitters and receivers to allow relatively modest symbol rates, the generation and detection of 112 Gb/s 16-QAM half-cycle Nyquist subcarrier modulation are considered using dual-polarization, single-carrier and single-polarization, dual-carrier implementations. High bandwidth directly modulated passive feedback lasers are used to generate the optical signals and pre-amplified receivers are used to detect the received signals in a back-to-back system and after transmission over 4 km of single-mode fiber.
