摘要： A light emitting device includes: a base having a recess and a flat upper surface; a light emitting element disposed on the upper surface of the base and configured to emit light laterally from an emission end surface; and a reflective member disposed on the upper surface of the base to face the light emitting element with the recess located between part of the reflective member and the light emitting element in a top view, the reflective member having a reflective surface configured to reflect the light upward. At least a portion of the reflective surface overlaps with the recess in the top view. A lower end of the reflective surface is located lower than the upper surface of the base and higher than a bottom surface of the recess in a direction normal to the upper surface of the base.

摘要： The present invention discloses a VCSEL array that can function in at least two different operational modes. In one operational mode, the VCSEL array functions as a regular-patterned array; and in the other operational mode, the VCSEL array functions as an irregular-patterned array. Thus, the same VCSEL chip may be used as an illumination light source or a structural light method light source for 3D sensing, depending on the selected operational mode.

摘要： An electrical pumping vertical external-cavity surface-emitting laser (EP-VECSEL) device. The device may comprise a bottom contact, a first distributed Bragg reflector (DBR) disposed on the bottom contact, and an active region comprising a plurality of emitters, disposed on the first DBR configured to accept an electrical current at multiple emitters on the active region such that the multiple emitters produce a plurality of lasers. The multiple emitters may be configured to form a desired Hermite Gaussian (HG) mode shape. The device may further comprise a second DBR disposed on the active region and a top contact disposed on the second DBR. The top contact may be shaped such that the plurality of lasers are directed through the top contact. The device may further comprise an array output coupler disposed optically in line with the top contact such that the plurality of lasers are directed into the array output coupler.
