摘要： VCSELs and methods having improved characteristics. In some embodiments, these include a semiconductor substrate; a vertical-cavity surface-emitting laser (VCSEL) on the substrate; a first electrical contact formed on the VCSEL; a second electrical contact formed on the substrate, wherein the VCSEL includes: a first resonating cavity having first and second mirrors, at least one of which partially transmits light incident on that mirror, wherein the first second mirrors are electrically conductive. A first layer is between the first mirror and the second mirror and has a first aperture that restricts the path of current flow. A second layer is between the first layer and the second mirror and also restricts the electrical current path. A multiple-quantum-well (MQW) structure is between the first mirror and the second mirror, wherein the first and second apertures act together to define a path geometry of the current through the MQW structure.

摘要： The present disclosure relates to a packaging approach for ensuring that high power optical modules incorporating VCSELs and VCSEL arrays remain eye safe. A VCSEL device or VCSEL package of the present disclosure may generally be configured certifying an optical device as eye safe such that the device is able to survive a single failure mode. In other embodiments, a multiple lens array is arranged above the VCSEL, which scatters the light into a wide range of angles such that a higher percentage of light will reach the photodetector located beside the VCSEL. In other embodiments according to the present disclosure, one or more methods and circuits are provided to detect and correct errors or failures caused by one or more unsafe conditions.
