Abstract: A method/system described herein addresses the intrinsic nonlinearity of electrooptic modulators and the restrictions placed on the signals dynamic range in applications such as data communication and sensing. Linear electro-optic modulation utilizing ring resonator electrooptic modulators is produced over a dramatically wider range of the input signal amplitude, which improves the dynamic range and the amount of information that is transmitted via laser light. A distributed and subranging design “folds” the large dynamic range across multiple linear subranges, with each subrange being addressed using a unique optical wavelength, or a unique optical fiber, or a unique free space path. The subrange within the wide dynamic range of the input signal is captured by the linear portion of the transfer function of a single transfer function. This enables the efficient use of optical links for the transmission and processing of analog and multilevel signals, overcoming the limitations that were hindering progress.

Abstract: Described herein is a system to convert laser light to electrical energy which exploits a narrow band nature of laser light, and a cavity resonance effect in order to increase an absorption of the laser light and thus, an efficiency in conversion of the laser light to electrical energy. For the resonant effect to take place in the photovoltaic cells, the laser wavelength emitted by the laser should match at least one of the resonant lines of the resonant cavity. A resonant cavity enhances an intensity of laser light inside the photovoltaic cell. The subject matter lowers a cost of the photovoltaic cell by making it possible to use a thinner (and more mechanically flexible) semiconductor for the photovoltaic cell while achieving the good laser light to power conversion efficiency.
