    Abstract: A photonically sampled analog-to-digital converter using parallel channels of sampling and quantizing. The parallel combination achieves cancellation of the spurs that result from the nonlinear transfer function of the samplers. The samplers feed a dual-detector optoelectronic receiver that has differential inputs for suppression of laser intensity noise. The outputs of the multiple photonic samplers are averaged to reduce the effects of shot or thermal noise from the optoelectronic receiver of a sampler. The errors produced by the quantization process can be reduced by using a delta-sigma modulator-based analog-to-digital convertor as the quantizer which provides noise-spectrum shaping and filtering.

    Abstract: An application-specific rf optoelectronic integrated circuit having a generic chip member and a defining substrate in communication with at least one generic chip member. The generic chip member contains passive building block components that are independent from each other and being connected by paths external to the generic chip member. The external connection paths are defined by a defining substrate member having passive components for providing optical and electrical interconnection between selected building block components on the generic chip member to define the specific function of the integrated circuit. It is possible to use the same design of the generic chip for several applications merely by altering the interconnect paths on a defining substrate.

    Abstract: An integrated optical transmitter includes a modulator drive circuit in communication with a modulator, and a laser drive circuit in communication with a laser. The modulator receives laser light from the laser and modulation control signals from the modulator drive circuit, and outputs modulated optical signals in a direction normal to the substrate surface. The transmitter is integrated by securing the laser to the modulator using flip chip technology. The laser includes a vertical cavity, and is optically aligned with the horizontal coupling surface of the modulator during the flip chip process.

    Abstract: A surface-emitting laser system includes a laser that emits a vertically divergent beam generally parallel to the substrate on which it is formed, and a turning mirror in the path of the beam that extends up from the substrate to a level well above the laser height. The extended mirror area reflects a greater portion of the beam than prior planar designs, increasing the output efficiency and providing a smoother beam pattern. One fabrication method employs a masking and ion beam milling technique that uses an accumulation of redeposited material to form the additional mirror area, with a thick mask layer that is later removed guiding the redeposition. An alternate fabrication method involves epitaxial growth of an additional layer of material above the conventional laser epilayers, with the additional layer subsequently removed from the laser region but retained in the mirror region.
