摘要： A visible wavelength vertical cavity surface emitting laser suitable for single mode operation has an oxide aperture (81, 82) for concentrating electrical current within a central axial portion (143) of the device and a surface relief feature (144, 146) at an output surface of the device selecting for substantially single lateral mode of operation. The relationship between oxide confinement structure diameter (140) and surface relief feature diameter (141) has been mapped to provide optimum conditions for single mode behaviour and define a region of that space to produce optimum device performance in the visible device operating wavelength band between 630 nm and 690 nm.

摘要： A connector (50) receives and grips an optical fibre (F) in registry with an optical element (53). Pivoting portions (22, 32) are held in default inoperative position by the spring action of moulded hinges (21, 31), at which position two shutter portions (24, 34) meet, so forming a shutter preventing the ingress of dirt to the optical element. This is the default position when the connector is not being used. As the optical fibre (F) is pushed a small distance into the connector, the pivoting portions (22, 32) are caused to pivot a small amount about the hinges (21, 22), bringing teeth (23, 33) into contact with the outside jacket of the fibre (F).The bodies (20, 30) of the inserts are forced radially away from the central axis of the connector, so providing a leaf spring force which keeps the teeth (23, 33) engaged with the jacket of the fibre (F). The shutter portions (24, 34) move out of the way of the fibre (F) and the spring action applies a force to draw the fibre (F) further into the body of the connector (50).When the fibre (F) has been pushed home the bodies of the inserts (20, 30) have been able to relax partially in the radial direction towards their normal position, but continue to exert a spring force on the teeth (23, 33). This force acts both to keep the teeth engaged in the jacket of the fibre, and to push the fibre F firmly against the optical element (53), so that the fibre F is held in the connector (50) in the engaged position.

摘要翻译：连接器（50）接收并夹持与光学元件（53）配准的光纤（F）。枢转部分（22,32）通过模制铰链（21,31）的弹簧作用保持在默认的非工作位置，在该位置两个活门部分（24,34）相遇，从而形成防止灰尘进入光学元件。这是连接器未被使用时的默认位置。当光纤（F）被推入连接器一小段距离时，使枢转部分（22,32）围绕铰链（21,22）枢转少量，使齿（23,33）与（F）的外部护套。插入物的主体（20,30）被径向地推离连接器的中心轴线，因此提供片簧弹力，其保持齿（23,33）与纤维外套（F）。遮光部分（24,34）移出光纤（F）的路径，并且弹簧作用施加力以将光纤（F）进一步拉入连接器（50）的主体中。当光纤（F）已经被推回到插入件（20,30）的主体已经能够朝着其正常位置的径向部分地部分地松弛，但是继续对牙齿（23,33）施加弹簧力。该力既用于保持啮合在光纤护套中的齿，又用于将光纤F牢固地推靠在光学元件（53）上，使得光纤F在连接器（50）中保持在啮合位置。
