摘要： The present invention relates to a technique for fabricating a mechanical or visual alignment fiducial on a laser die particularly adapted for application with a laser die that is a buried structure edge emitting laser. In fabricating the device, the fiducial and the active mesa are formed in the same photolithography patterning step, using conventional techniques. The active is then buried with regrowth layers. The regrowth layers are subsequently selectively etched to expose the fiducial, leaving the active region protected and buried.

摘要： A package for an optoelectronic device having an optical fiber in communication therewith. The parts of the package are generally of polymer material, preferably engineering thermoplastic, which is assembled to the fiber having the device mounted on a printed circuit board type material, FR4. The adhesion process of the individual parts of the package is done typically through a solvent bonding or an epoxy curing process that is done at room temperature, thereby eliminating the drawbacks of soldering at high temperature which has the attendant disadvantage of built in stress and thermal expansion resulting in misalignment of the individual parts. The related packaging technique greatly reduces the requirements of active alignment of the fiber to the device in the packaging of the device and fiber. Accordingly, the overall cost of the device is reduced by virtue of the reduced cost of the parts of the package as well as the process for fabrication of the package.

摘要： Light emitting devices are requiring greater switching speeds to achieve greater modulation bandwidths. The problems of intrinsic capacitance associated with conventional semiconductor heterojunction devices are reduced by the reduction of pn junction capacitance as well as the use of a semi-insulating blocking layer and a conductive substrate. Furthermore, a light absorbing layer is disposed on one side of an unetched portion of the semi-insulating material and an active layer disposed on opposite side. Also, the interface of the semi-insulating material and the active and absorbing layers are at prescribed angles that reduce back reflections to the absorbing and active layers. This arrangement reduces pumping in the absorbing region and thus reduces the lasing effect, allowing for a stable LED. The angle at the interface is determined by having the structure at a predetermined crystallographic direction and having the semi-insulating mesa etched to reveal a predetermined crystalline plane. Finally, in one embodiment of the invention, a channel is etched and filled with thermally conductive material to dissipate heat. This channel, in addition to the heat dissipation effected by the semi-insulating material enables a near linear light output versus current input characteristic for the device.
摘要翻译：发光器件需要更高的开关速度来实现更大的调制带宽。通过减少pn结电容以及使用半绝缘阻挡层和导电衬底来减少与常规半导体异质结器件相关的本征电容的问题。此外，在半绝缘材料的未蚀刻部分的一侧和设置在相对侧的有源层上设置光吸收层。此外，半绝缘材料和主动和吸收层的界面处于规定的角度，减小了对吸收层和活性层的反射。这种布置减少了吸收区域中的泵送，从而降低了激光效应，从而允许稳定的LED。界面处的角度通过使结构处于预定的晶体方向并且具有半绝缘台面蚀刻以露出预定的晶面来确定。最后，在本发明的一个实施例中，蚀刻通道并填充导热材料以散热。除了由半绝缘材料实现的散热之外，该通道能够实现近似线性的光输出与器件的电流输入特性。

摘要： The invention relates to ridge waveguide semiconductor diode lasers that include a substrate, a first cladding layer near the substrate, a second cladding layer near the first cladding layer, and an active layer between the first cladding layer and the second cladding layer and extending the distance between a first facet and a second facet of the diode laser. The diode laser includes a cap layer located near the second cladding layer, a ridge formed in the cap layer and the second cladding layer, and a contact layer applied at least at the ridge for injecting current into the active layer. The contact layer contacts the cap layer in a contact region having a length that is less than the distance between the first facet and the second facet such that the cap layer includes an unpumped facet region. Methods to make the new lasers are also described.
