    • Methods are disclosed for producing a tunable vertical cavity surface emitting laser (VCSEL) using photonic crystals and an electrostrictive material that includes a hologram with a narrow filter function. Photonic crystals are formed such that the active region of the VCSEL is bounded by the photonic crystals. The photonic crystals have a periodic cavity structure that reflects light of certain wavelengths through the active region of the VCSEL such that laser light at the wavelengths is generated. The periodic cavity structure includes a central defect that does not include any cavities. The single mode is emitted through the central defect. The electrostrictive material that includes a hologram makes the VCSEL tunable because the shape of the electrostrictive material changes when an electric field is applied. The filter function of the hologram thus changes as well in response to the electric field such that the VCSEL is tunable.
    • 公开了用于使用光子晶体生产可调谐垂直腔表面发射激光器(VCSEL)的方法和包括具有窄滤波器功能的全息图的电致伸缩材料。 形成光子晶体,使得VCSEL的有源区域被光子晶体限制。 光子晶体具有通过VCSEL的有源区域反射某些波长的光的周期性空腔结构,使得产生波长的激光。 周期性空腔结构包括不包括任何空腔的中心缺陷。 单一模式通过中心缺陷发射。 包括全息图的电致伸缩材料使得VCSEL可调谐,因为当施加电场时电致伸缩材料的形状改变。 因此,全息图的滤波器功能也响应于电场而改变,使得VCSEL是可调谐的。

    • This disclosure concerns optical packages such as may be used in optical transceivers and transmitters. In one example, an optical package includes a header assembly having a base portion to which is attached a header structure that is split into first and second portions that are separated from each other by a space. The header structure further includes one or more electrical leads extending through the base portion and into one of the first and second portions of the header structure. An active temperature control device is included in the optical package and resides in the space between the first and second portions of the header structure. Finally, an optical element, such as a laser, is provided that is arranged for thermal communication with the active temperature control device so that operation of the optical element can be controlled by way of the active temperature control device.

    • A laser system that can be used to perform manufacturing process such as welding, cutting, drilling and marking a work piece. The laser system includes an array of laser diodes that each generate a laser beam. The laser beams may collectively create a beam that is directed onto the work piece. The system also includes a control circuit that can select and control the laser diodes to vary a characteristic(s) and/or profile of the beam. The control circuit may control the laser diodes so that an outer area of the beam has a higher intensity than an inner area of the beam.
    • 可用于执行焊接,切割,钻孔和标记工件等制造工艺的激光系统。 激光系统包括激光二极管阵列,每个激光二极管都产生激光束。 激光束可以共同地产生被引导到工件上的光束。 该系统还包括可以选择和控制激光二极管以改变光束的特性和/或轮廓的控制电路。 控制电路可以控制激光二极管,使得光束的外部区域具有比光束的内部区域更高的强度。
