Optical structure for imparting a distributed phase shift to an optical signal, electro-optic modulator incorporating such structure for reduced size, low signal loss, and high extinction ratio, and related system and method

摘要

An embodiment of an optical structure includes a core having first and second ends and a first side with a first grating profile having a first phase shift distributed between the first and second ends, and a cladding disposed around the core. Such an optical structure can be used in an electro-optic modulator (EOM), and can render the EOM smaller in size than currently available EOMs.
