20130064263 | VERTICAL CAVITY SURFACE EMITTING LASER AND MANUFACTURING METHOD THEREOF - The present invention discloses a manufacturing method of vertical cavity surface emitting laser. The method includes following steps: providing a substrate; forming an epitaxial layer stack including an aluminum-rich layer; forming an ion-doping mask including a ring-shaped opening; doping ions in the epitaxial layer stack through the ring-shaped opening and forming a ring-shaped ion-doped region over the aluminum-rich layer; forming an etching mask on the ion-doping mask for covering the ring-shaped opening of the ion-doping mask; etching the epitaxial layer stack through the etching mask and ion-doping mask for forming an island platform; oxidizing the aluminum-rich layer for forming a ring-shaped oxidized region. In addition, the present invention also discloses a vertical cavity surface emitting laser manufactured by the above mentioned method. | 03-14-2013 |
20130032701 | INPUTTING MODULE AND SUBMOUNT THEREOF AND MANUFACTURING METHOD OF THE SUBMOUNT - A submount is used for disposing an illuminant element or a light-receiving element having an optical axis. The submount is disposed at a plane and has a main body. The main body includes a first surface and a second surface. The first surface is approximately parallel to the plane and far away from the plane. The second surface is approximately parallel to the plane and adjacent to the plane. A disposing part of the first surface is tilted with respect to the second surface at a predetermined angle. The illuminant element or the light-receiving element is disposed on the disposing part. The optical axis of the illuminant element or the light-receiving element is tiled with respect to a normal of the second surface at the predetermined angle. | 02-07-2013 |
20130015334 | OPTICAL INPUTTING MODULE AND ITS LIGHT SOURCE UNITAANM CHEN; Chih-ChengAACI Zhongli CityAACO TWAAGP CHEN; Chih-Cheng Zhongli City TWAANM Pan; Jin-ShanAACI Hsinchu CityAACO TWAAGP Pan; Jin-Shan Hsinchu City TW - A light source unit is disclosed for arranging on a plane and emitting a light beam oblique to the plane. The light source unit includes an illuminant element and a transparent encapsulator. The illuminant element has an upper surface and a lower surface both parallel to the plane. The transparent encapsulator physically contacts with the illuminant element and at least covers the upper surface of the illuminant element. The transparent encapsulator has an oblique surface above the upper surface and oblique to the upper surface. In addition, an optical inputting module having the light source unit mentioned above is disclosed. | 01-17-2013 |
