Abstract: An optical modulator includes: a bottom reflective layer; an active layer which is disposed on the bottom reflective layer and includes a multiple quantum well layer; and a top reflective layer which is disposed on the active layer, the top reflective layer including a first top reflective layer which is disposed on the active layer, a first cavity layer which is disposed on the first top reflective layer, a second top reflective layer which is disposed on the first cavity layer, a second cavity layer which is disposed on the second top reflective layer, and a third top reflective layer which is disposed on the second cavity layer. When a center wavelength of an incident light to be modulated is λ, the active layer and the first and second cavity layers have an optical thickness that is an integer multiple of λ/2 to provide an individual resonant cavity.

Abstract: An imaging device includes at least a first group of pixels. A driver block is configured to generate at least two shutter signals, each having on-phases periodically alternating with off-phases. The shutter signals might not be in phase. The imaging device may have an optical shutter that is partitioned in two or more parts, or a set of two or more optical shutters. The shutter parts, or the shutters, may receive the shutter signals, and accordingly open and close. A design of the driver block requires reduced power, which is highly desirable for mobile applications. Moreover, 3D imaging may be implemented that uses various time-of-flight configurations.

Abstract translation: 成像装置至少包括第一组像素。 驱动器块被配置为产生至少两个快门信号，每个快门信号具有与非相位周期性交替的同相。 快门信号可能不同相。 成像装置可以具有分成两部分或更多部分的光学快门，或者一组两个或更多个光学百叶窗。 快门部件或百叶窗可以接收快门信号，并因此打开和关闭。 驱动器块的设计需要降低功率，这对于移动应用是非常需要的。 此外，可以实现使用各种飞行时间配置的3D成像。
