Ultracompact, High-Speed Field-Effect Optical Modulators (Research Topic 4.2 Optoelectronics)
Abstract
One of the technical barriers impeding the wide applications of integrated photonic circuits is the lack of ultracompact, high speed, broadband electro-optical (EO) modulators, which up-convert electronic signals into high bit-rate photonic data. In addition to direct modulation of lasers, EO modulators can be classified into (i) phase modulation based on EO effect or free-carrier injection [1, 2], or (ii) absorption modulation based on Franz-Keldysh effect or quantum-confined Stark effect [3-7]. Due to the poor EO properties of regular materials, a conventional EO modulator has a very large footprint.
