摘      要：Optical links are moving to higher and higher transmission speeds while shrinking to shorter and shorter ranges where optical links are envisaged even at the chip *** scaling in data speed and span of the optical links demands modulators to be concurrently performant and *** photonics(SiPh),a photonic integrated circuit technology that leverages the fabrication sophistication of complementary metal-oxide-semiconductor technology,is well-positioned to deliver the performance,price,and manufacturing volume for the high-speed modulators of future optical communication *** has relied on the plasma dispersion effect,either in injection,depletion,or accumulation mode,to demonstrate efficient high-speed *** high-speed plasma dispersion silicon modulators have been commercially deployed and have demonstrated excellent *** years have seen a paradigm shift where the integration of various electro-refractive and electro-absorptive materials has opened up additional routes toward performant SiPh *** modulators are in the early years of their *** promise to extend the performance beyond the limits set by the physical properties of *** focus of our study is to provide a comprehensive review of contemporary(i.e.,plasma dispersion modulators)and new modulator implementations that involve the integration of novel materials with SiPh.
