摘要： A surface emitting laser with spatially varying optical loss to provide single mode operation. The optical loss may be introduced with an anti-phased ohmic contacts (4, 5). Current injection may be constricted to a diameter that is different than the diameter of the ohmic aperture (32), allowing for optimization of carrier profiles for high-speed performance. Methods for index guiding are introduced to further the reproducibility of the invention.

摘要： An opto-electronic coupling assembly (10) for optically coupling a light active area of an active device (12) with an end face that is disposed at one end of an elongated light guide such that light is coupled between the end face of the light guide end housing (14) that defines a housing outline and which is adapted to support the end of the light guide including its end face. The opto-electronic coupling assembly (10) further includes an active device (12) and at least partially surrounds the support arrangement. The encapsulant material (34) is substantially optically transparent to the coupled light and is molded in a predetermined configuration which cooperates with the housing outline of the light guide end housing in a way that passively places the light guide when the light guide end housing (14) is assembled with the active device (12) package.

摘要： A vertical cavity surface emitting laser, VCSEL, (2) with variable tuning layer (10) for adjusting the slope of the laser (2) and method for manufacturing the same are disclosed. In practice, a VCSEL wafer is grown by any conventional technique, and fabricated into discrete lasers (2) while maintained in wafer form. The initial lasers (2) are then tested to determine characteristics, such as the slope efficiency distribution to within a target specification by altering the phase of the top facet reflectivity of the initial lasers (2). The resulting change in transmission directly changes the laser slope in a predictable fashion. The tuning step may be repeated, if necessary, to further refine the slope to the desired value. The method produces VCSELs (2) with similar or consistent slopes from a plurality of wafers. Also disclosed are an optical subassembly (110) and optical transceiver (130) incorporating the improved VCSELs.

摘要： A multilayer ceramic carrier for an optical element includes a terraced cavity for retaining a vertically receiving or vertically emitting optical element. The multilayer ceramic carrier includes conductive traces interposed between the ceramic layers and which extend into the terraced cavity along the trenches formed in the cavity. A vertical cavity surface emitting laser or vertically receiving optical element is wire bonded to the conductive traces which extend into the cavity. In one embodiment, the terraced cavity of the multilayer ceramic carrier includes a VCSEL and photodetector therein, the photodetector capable of monitoring the output optical power of the VCSEL. The method for forming the multilayer ceramic carrier includes forming a plurality of layers of ceramic tape, joining the layers, then c-firing the stacked layers. The multilayer ceramic carrier is joined to a plastic housing which includes an aperture for securing an optical fiber. The fiber launch direction is generally orthogonal to the optical surface of the vertically emitting or vertically receiving optical element secured within the ceramic carrier. The optical subassembly comprising the plastic optical housing and ceramic carrier is mounted on the surface of a printed circuit board or adjacent the edge of a printed circuit board, such that the light emitted or detected by the optical element, preferably travels along a fiber launch direction parallel to the surface of the printed circuit board. The optical assembly may be joined to the printed circuit board using various connectors capable of carrying an electrical signal.

摘要： Selectively oxidized vertical cavity lasers (900) emitting at about 1290 nm using InGaAsN quantum wells that operate continuous wave. The lasers (900) employ a semi-insulating GaAs substrate (910) for reduced capacitance, high quality, low resistivity AlGaAs DBR mirror structures (920, 970), and a strained active region (18) based on InGaAsN. In addition, the design of the VCSEL (900) reduces free carrier absorption of 1300 nm light in p-type materials (950) of the lasers by placing relatively high p-type dopant concentrations (952(a), 952(b)) near standing wave nulls (980).

摘要： A monolithically integrated VCSEL and photodetector, and a method of manufacturing the same, are disclosed for applications where the VCSEL and photodetector require separate operation such as duplex serial data communications applications. A first embodiment integrates a VCSEL with an MSM photodetector on a semi-insulating substrate. A second embodiment builds layers of a p-i-n photodiode on top of layers forming a VCSEL using a standard VCSEL process. The p-i-n layers are etched away in areas where VCSELs are to be formed and left where photodetectors are to be formed. The VCSELs underlying the photodetectors are inoperable, and serve to recirculate photons which are not initially absorbed back into the photodetector. The transmit and receive pairs are packaged into a single package for interface to multifiber ferrules. The distance between the devices is precisely defined photolithographically, thereby making alignment easier. In a further alternate embodiment, an FET is coupled to the p-i-n photodiode to form an integrated detector preamplifier along with the VCSEL transmitter all on the same optical reference plane.
摘要翻译：公开了一种单片集成VCSEL和光电检测器及其制造方法，其中VCSEL和光电检测器需要单独的操作，例如双工串行数据通信应用。第一实施例将VCSEL与半绝缘衬底上的MSM光电检测器集成。第二实施例使用标准VCSEL工艺在形成VCSEL的层之上构建p-i-n光电二极管的层。在要形成VCSEL的区域中蚀刻掉p-i-n层，并留下要形成光电探测器的区域。光电探测器下面的VCSEL是不可操作的，并且用于使最初未被吸收回光电检测器的光子再循环。发送和接收对被封装成单个封装，用于与多光纤套管接口。设备之间的距离是光刻的精确定义，从而使对准更容易。在另一替代实施例中，FET耦合到p-i-n光电二极管，以形成集成的检测器前置放大器以及VCSEL发射器全部在相同的光学参考平面上。
