In this paper, a process is outlined for the integration of commercial bare die VCSEL and PiN PDs embedded in polymer waveguide on inexpensive printed wiring board (PWB) boards. The evanescent coupling efficiency of both PiN and metal-semiconductor-metal (MSM) PD from Siloxane waveguide is measured. This is the first demonstration of a process for embedding commercial PiN PDs in polymer waveguide for high speed chip to chip optical interconnects. Optoelectronic devices embedded in Siloxane waveguide on FR4 board such as embedded MSM PD in waveguide, PiN PD embedded in waveguide, embedded VCSEL and PiN on board and embedded VCSEL in waveguide with end mirror.

Deformed liquid-jet microcavity of low index of refraction has advantages of enabling continuous deformation of cavity, easy control of gain molecule concentration and highly smooth surface due to surface tension. These cavities have been shown to support scarred modes of cavity Q in the range of 10/sup 6/ with directional emission consistent with an unstable periodic orbit that the scar modes correspond to. We demonstrated theoretically and experimentally that by selecting the pump laser direction properly one can maximize the coupling between the pump laser and the scarred modes in a liquid-jet quadrupole-deformed microcavity, thereby maximizing lasing efficiency. We directly observed that the output emission emerged from the locations on the cavity surface which correspond to the corners of the unstable periodic orbit, with its direction tangential to the cavity surface via evanescent tunneling mechanism, resulting in collimated directional output.

In this paper, a miniaturized continuously tunable optical true-time-delay module has been designed, fabricated and evaluated for integrating into a X-band 4X4 2-D phased array antenna system. A novel symmetric structure is introduced to keep the output beam position fixed and avoid using a set of large collimators. This new structure is compact and easy to package while providing doubled delay time. Therefore, this module can easily scale up for large arrays due to its compressive structure.

In this paper, the first report of a photodetector embedded in a polymer waveguide with output to a Si-Ge transimpedance amplifier is reported. This system was tested with an endfire coupled optical input to the multimode polymer waveguide, and, through direct coupling of this light to the photodetector from the waveguide followed by photodetector current output to a Maxim Si-Ge transimpedance amplifier, operation of this interconnection channel at 2.5 Gbps has been demonstrated.

In this paper, the design and testing of a 2.5 Gb/s VCSEL driver for short-to-medium reach optical interconnects is outlined. With the ever increasing processing capacity of digital systems, electrical interconnects linking CMOS chips have become the limiting performance factor. Optical interconnects have been proposed as a promising alternative to increase interconnect capacity. Although vertical-cavity surface-emitting lasers (VCSEL) are well suited for such an application, high-speed VCSEL drivers reported in the literature generally consume a significant amount of power.

In this paper, we describe the experiment and review our results to date. Degraded VCSEL arrays have been censored and are currently being subjected to a detailed physical characterization. This analysis will provide a glimpse into the manifestation of VCSEL failures, the mechanisms and physics of emission degradation. Optical interconnects will be required for the bandwidth needs for computing systems in the near future. We have investigated the specific parameters that produce the most reliable VCSELs - the emitter engines for optical interconnects.

Photonic crystal fibers (PCFs) provide large dispersion tuning ability by increasing the dispersion value to reduce the fiber length. With conventional single-mode fibers (SMFs), dispersion cannot be changed significantly because of the small index variation from doping over the transverse cross section. This shortcoming may be overcome by the design of PCFs, which can be tailored to exhibit high dispersion. The novel cladding structure of PCFs consisting of an array of micrometer-sized air holes allows for flexible tailoring of the dispersion curve.
