    摘要: A tunable semiconductor laser system includes a laser with a semiconductor active region positioned between upper and lower confining regions of opposite type semiconductor material. First and second reflective members are positioned at opposing edges of the active and confining regions. A wavelength tuning member and a temperature sensor are coupled to the laser. A control loop is coupled to the temperature sensor and the tuning member. In response to a detected change in temperature the control loop sends an adjustment signal to the tuning member and the tuning member adjusts a voltage or current supplied to the laser to provide a controlled output beam of selected wavelength.

    摘要: A tunable semiconductor laser assembly includes a laser with a seal surface, a semiconductor active region positioned between upper and lower confining regions of opposite type semiconductor material and first and second reflective members positioned at opposing edges of the active and confining regions. A seal cap includes a seal ring. The seal cap seal ring is coupled to the seal surface and forms a hermetic seal. A wavelength tuning member and a temperature sensor is coupled to the laser. A temperature sensor coupled to the laser. A control loop is coupled to the temperature sensor and the tuning member. In response to a detected change in temperature the control loop sends an adjustment signal to the tuning member, and the tuning member adjusts a voltage or current supplied to the laser to provide a controlled frequency and power of an output beam.

    摘要: The present invention provides multiple-wavelength vertical-cavity surface-emitting laser (“MW-VCSEL”) arrays. These arrays are fabricated in a molecular beam epitaxy system or the like using two patterned-substrate growth techniques. The growth techniques can be used with an in-situ laser reflectometry. In one embodiment, a temperature dependent growth rate to create the devices is provided. In an alternative aspect, uniform growth is performed followed by a temperature-dependent desorption technique. These techniques provided desired wavelength span and desired characteristics.

    摘要: A monolithic vertical optical cavity device built up along a vertical direction. The device has a bottom Distributed Bragg Reflector (DBR), a Quantum Well (QW) region consisting of least one active layer grown on top of the bottom DBR by using a Selective Area Epitaxy (SAE) mask such that the active layer or layers exhibit a variation in at least one physical parameter in a horizontal plane perpendicular to the vertical direction and a top DBR deposited on top of the QW region. A spacer is deposited with or without SAE adjacent the QW region. The device has a variable Fabry-Perot distance defined along the vertical direction between the bottom DBR and the top DBR and a variable physical parameter of the active layer. The varying physical parameter of the active layers is either their surface curvature and/or the band gap and both of these parameters are regulated by SAE. The monolithic vertical cavity device can be used as a Vertical Cavity Surface Emitting Laser (VCSEL) or a Vertical Cavity Detector (VCDET).
