Optical modulator for a three-dimensional camera |
摘要 |
Optical modulator having wide bandwidth based on Fabry-Perot resonant reflection is disclosed. The optical modulator includes: a bottom Distributed Bragg Reflector (DBR) layer (110); a top DBR layer (130) including at least one layer and a modified layer; and an active layer (120) disposed between bottom and top DBR layers, wherein the at least one layer includes at least one pair of a first refractive index sub-layer having a first refractive index and a second refractive index sub-layer having a second refractive index, the modified layer includes at least one pair of a third refractive index sub-layer having a third refractive index and a fourth refractive index sub-layer having a fourth refractive index, the third and the fourth refractive indexes being different, and at least one of the third and the fourth refractive index sub-layers have a second optical thickness that is not »/4 or that is not an odd multiple thereof. |
