Abstract: The present invention relates to a solid-state laser comprising: a) a semiconductor pump laser, b) a lens integrated on the surface of said semiconductor pump laser, c) a packaging material consisting essentially of a spin-on glass material, wherein the spin-on glass material is processable at a process temperature of less than 225° C., and d) a lasing material layer having a highly reflective coating in both sides. The invention also relates to a process for producing such a solid-state laser, which process comprises applying spin-on glass material onto semiconductor wafers having VCSEL pump lasers using different coating methods, such as spin coating, and curing the glass film layer at temperatures <225° C.

Abstract: The subject invention relates to the fabrication of micro-optical structures in a glass-like transparent material using conventional photolithography processing steps. The glass-like material is a spin-on glass (SOG) material, which behaves like a negative-tone photoresist, and has high quality optical properties similar to those of glass. The present invention can take advantage of gray scale photomasks to illuminate the uncured spin-on material with various illumination intensities, thus resulting in variations in resultant film thickness of the SOG material after the chemical development step. This results in micro-optical structures that can be fabricated with the desired shapes, depending on the transmission characteristics of each region of the gray scale photomask.

Abstract: An optoelectronic device having a flexible substrate and an optical interconnect (i.e. waveguide) comprising a sol-gel based material formed on the substrate. The sol-gel based waveguide is capable of being integrated into an all-optical system and provides for greater interconnect distance and lower signal loss. Other sol-gel based optical devices, such as filters, optical source, detectors, sensors, switches and the like, will be implemented in conjunction with the sol-gel based waveguides to provide for an integrated optical system. Methods of formulating the sol-gel based material and methods for fabricating the sol-gel based devices are also provided.

Abstract: The present invention claims a unique way to pattern an optical microstructure immediately on top of a mass produced light-emitting device, such as a light emitting diode (LED), a vertical cavity surface emitting laser (VCSEL) or a photo detector, for the purpose of efficient coupling of light to or from the active region of the light-emitting device. The invention addresses the need to effectively and efficiently extract light from the light-emitting optoelectronic device. Finally, the invention allows for the optical microstructure to be deposited and patterned directly over the light-emitting device contained on a suitable substrate, such as a wafer.
