摘要： A green LED has a substrate, a GaN heavily n-doped bottom confining layer, an active region, an upper GaN confinement layer, and a semi-transparent ohmic contact layer. The active region has less than or equal to three highly compressively strained quantum wells. The widths of the quantum wells is less than 3 nm. The active region arrangement provides a short free carrier life-time and hence an increase in the modulation bandwidth of the LED.

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 be 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： An optical emitter assembly is described in which one or more optical devices each having an emitting aperture at a surface thereof can be mounted on a carrier such that the plane of the emitting apertures with respect to a well defined reference plane can be precisely controlled. This enables additional optical elements to be precisely axially and laterally positioned with respect to the centre of the emitting apertures, even when there are plural optical devices of differing thicknesses. The assembly may comprise a surface-emitting optical device having an emission surface providing an optical output aperture; a carrier having first and second opposing surfaces, the first surface being a reference surface on which the optical device is mounted by its emission surface and the second surface being a back surface, the carrier having an aperture extending between the reference and back surfaces, the optical device being positioned on the reference surface such that its optical output aperture is in overlying relation with the carrier aperture to direct optical radiation therethrough.

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.
