The Advantages of Indium Phosphide Photonic Integration in High-performance Coherent Optics

A wide range of cloud and video applications, together with the increased access speeds enabled by 5G, DAA, and next-generation PON, are driving the need for ever more optical bandwidth. To deliver this bandwidth, optical vendors are developing a broad range of coherent optical transceivers addressing different segments of the market, each with its own set of design considerations. This white paper focuses on the high-performance segment, with ever-higher baud rates, higher-order modulation, and advanced capabilities such as Nyquist subcarriers and probabilistic constellation shaping that deliver more capacity per wavelength and increased spectral efficiency while maximizing reach.
