Abstract The rocketed development concerning electro-optic polymers fundamentally motivated by its pragmatic application in envisioning second-order nonlinear optics and waveguiding are cardinal. Modern synthetic strategies consigned an outstanding optical quality amorphous with enhanced properties. Documented data revealed a huge progress understanding their implementation, however challenges still exist regarding temporal stabilities etc. This review delivers brief investigation of (NLO)...
Digitalizing optical signals through electric driving signals, electro-optic modulators (EOMs) are one of the cardinal elements in modern communications. Most current EOM devices targeting on-chip integrations, which routinely suffer from high coupling losses, complex alignments and single-band operations.
