摘要: A surface-emitting laser contains an optical cavity including a multiple quantum well (MQW) active region providing a source of optical emission in use. Top and bottom mirrors are disposed respectively above and below the MQW active region. The MQW active region is profiled so that it has a greater number of quantum wells in a central portion thereof than in a peripheral portion thereof. In alternative embodiments, a current-guiding region is profiled so that it has a first current-guiding portion with a relatively smaller aperture therethrough extending over a central portion of the MQW active region, and a second current-guiding portion with a relatively larger aperture therethrough; and one of the mirrors has a layer structure which, in a central portion of the cross-sectional area of such mirror, is different to that in a peripheral portion of said cross-sectional area.

摘要: A single cavity mode optoelectronic device, such as a VCSEL, an RCLED or a DFB laser diode, comprises an etched-pillar or mesa structure including an optically active region and strain-applying means in the form of a layer of polymer material having a coefficient of thermal expansion which is greater than that of the optically active region. The layer surrounds the optically active region so as to apply a compressive strain to the latter so as to compensate at least partially for temperature-induced changes in the gain spectrum peak of the optically active region caused by ohmic heating of the device.

The array can be arranged as a parallel addressable system so that all devices (24) can be stimulated to emit light simultaneously. Alternatively, the array can be arranged as a matrix addressable array, in which case individual devices can be selectively stimulated.

摘要: The light emitted by diodes of the Gallium Nitride type which comprises two distinguishable emissions is controlled by a single optical element (10) in the form of a lens having a central part and an annular part with different optical powers. The total output light of the diode may be collimated or brought to a common focus. The single optical element is preferably injection moulded and the annular part takes the form of a diffraction lens. The first part (12) is preferably a refractive lens which has a different optical power to the second part (14)which is preferably a diffractive lens. The optical power of the refractive lens (12) (the first optical power) and the optical power of the diffractive lens (14) (the second optical power) are selected to match the light source that the lens (10) is to be used with.
