[vc_row][vc_column][vc_column_text]In addition to the intensity, information can be encoded on the phase, frequency, and polarization of an electromagnetic wave to carry information. Advanced modulation formats utilize a combination of these properties to increase the data carrying capacity of transmission channels. Corresponding transmitters and receivers require many functions such as intensity modulators, phase modulators, phase shifters, optical hybrids, balanced photodetectors, delay lines, and polarization control elements. Integrated photonics is therefore an ideal candidate for incorporating these functions in a compact form factor on a single chip. In addition to impacting communication systems in long-haul, metro, and free space networks, these transceivers, including coherent implementations, are expected to impact data center networks in the near future.<\/p>\n
