摘要： An integrated laser-based light source that generates an output light beam having a controlled intensity. The light source comprises a package, a laser, a light sensor, and a beam splitter. The beam splitter is mounted in the package, together with the laser and the light sensor. The laser has one and only one light-emitting face from which it radiates a light beam as a radiated light beam. The light sensor generates an electrical signal representing the intensity of light energy falling on it. The beam splitter divides the radiated light beam into a fraction and a remainder, the remainder being the output light beam. The beam splitter operates by diffraction, scattering, or transmission to direct the fraction of the radiated light beam towards the light sensor.

摘要： An integrated laser-based light source that generates an output light beam having a controlled intensity. The light source comprises a package in which are mounted a laser, a light sensor and a coupler. The laser has one and only one light-emitting face from which a light beam is radiated as a radiated light beam. The light sensor generates an electrical signal representing the intensity of light energy falling it. The coupler couples a fraction of the radiated light beam to the light sensor, and provides the remainder of the radiated light beam as the output light beam. Since the light coupled to the light sensor by the coupler is a fraction of the radiated light beam, the electrical signal generated by the light sensor also represents the intensities of the radiated light beam and of the output light beam. A suitable control circuit, when fed with the electrical signal generated by the light sensor, can control the laser current to hold the electrical signal generated by the light sensor to a predetermined value that corresponds to the output light beam having a predetermined intensity.
摘要翻译：一种集成的基于激光的光源，其产生具有受控强度的输出光束。光源包括其中安装有激光器，光传感器和耦合器的封装。激光器具有一个且仅一个发光面，光束从该发光面照射为辐射光束。光传感器产生表示落在其上的光能强度的电信号。耦合器将辐射光束的一部分耦合到光传感器，并且将辐射光束的其余部分提供为输出光束。由于通过耦合器耦合到光传感器的光是辐射光束的一部分，所以由光传感器产生的电信号也表示辐射光束和输出光束的强度。合适的控制电路当馈送由光传感器产生的电信号时，可以控制激光电流以将由光传感器产生的电信号保持在与具有预定强度的输出光束对应的预定值。

摘要： An integrated laser-based light source that generates an output light beam having a controlled intensity. The light source comprises a light sensor, a laser, a convex beam-splitting surface, and a package that includes a header. The light sensor generates an electrical signal representing an intensity of light energy falling on it, and is mounted on the header. The laser has one and only one light-emitting face from which a light beam is radiated as a radiated light beam. The laser is mounted in the package adjacent the light sensor with the light-emitting face substantially parallel to the light-receiving face of the light sensor. The convex beam-splitting surface reflects a fraction of the radiated light beam towards the light sensor as a reflected light beam, and transmits the remainder of the radiated light beam as the output light beam. The convex beam-splitting surface is supported in the radiated light beam by the package.

摘要： A Vertical Cavity Surface-Emitting Laser (VCSEL) assembly in which the polarization is locked to a specified direction that is the same for all VCSELs. A VCSEL according to the present invention includes a VCSEL having a top mirror region, a bottom mirror region, a light generation region between the top and bottom mirror regions, a conducting substrate and a bottom electrode. The bottom mirror region is sandwiched between the conducting substrate and the light generation region, and the conducting substrate is sandwiched between the bottom electrode and the bottom mirror region. The assembly also includes a mounting substrate having top and bottom surfaces, the VCSEL being mechanically coupled to the mounting substrate. The mounting substrate includes a means for defining a first axis. The assembly includes a means for causing the mounting substrate to flex about the first axis thereby inducing a strain in the light generation region which locks the polarization into a mode determined by the first axis. In one embodiment of the present invention, the first axis is defined by a channel in the mounting substrate. The mounting substrate is caused to flex by the application of an adhesive layer applied between the mounting substrate and a mounting surface. The adhesive layer has a thermal coefficient of expansion different from the mounting substrate. In another embodiment, trenches whose direction defines the first axis are located in the top mirror region of the VCSEL.

摘要： The present invention provides a n-drive surface emitting laser comprised of an active region, a first mirror region having a first conductivity type, a second mirror region having a second opposite conductivity type, the first and second mirror regions being located on opposite sides of the light generation region, a buffer region having a second conductivity type, and a substrate having a first conductivity type. In the preferred embodiment the first conductivity type is n-type, thus the present invention provides a method of forming an n-drive semiconductor laser on an n-type substrate. Contact is made to the p-type mirror region via a tunnel junction formed by degeneratively doping the areas of the substrate region and the buffer region which abut each other. The tunnel junction is reverse biased so that current is injected through the degeneratively doped p-n junction formed by the n+ substrate and the p-type conducting layer.

摘要： A substantially n-type substrate structure having a p-type surface for use in semiconductor devices as a substitute for a p-type semiconductor substrate. The substrate structure comprises a substrate region and a buffer region. The substrate region is a region of n-type compound semiconductor, and includes a degeneratively n-doped portion adjacent its first surface. The buffer region is a region of compound semiconductor doped with a p-type dopant. The buffer region is located on the first surface of the substrate region and includes a surface remote from the substrate region that provides the p-type surface of the substrate structure. The buffer region also includes a degeneratively p-doped portion adjacent the degeneratively n-doped portion of the substrate region. The substrate structure includes a tunnel junction between the degeneratively n-doped portion of the substrate region and the degeneratively p-doped portion of the buffer region. The substrate structure is made by degeneratively doping a substrate region of n-type compound semiconductor material adjacent its first surface with an n-type impurity, and depositing a layer of compound semiconductor material doped with a p-type impurity on the first surface of the substrate region to form a buffer region that includes a surface remote from the substrate region. In the course of depositing the compound semiconductor material to form the buffer region, the compound semiconductor material is degeneratively doped with the p-type impurity at least in a portion adjacent the substrate region to form a tunnel junction between the substrate region and the buffer region.
