摘要： A vertical cavity surface emitting laser (VCSEL) using photonic crystals with a central defect. At least one of the mirror layers of a VCSEL includes a photonic crystal with a central defect. The central defect, which is surrounded by a periodic structure of holes or cavities, permits laser light to propagate and exit the VCSEL. Semi-insulating regions are formed in the active region such that when cavities are drilled in the photonic crystal and penetrate the active region, the cavities pass through the semi-insulating regions. This reduces the surface recombination that would otherwise occur in the active region and prevents the threshold current from increasing. The photonic crystal with a central defect has a reflectivity that is wavelength dependent. The VCSEL thus emits a single mode.

摘要： Vertical cavity surface emitting lasers are disclosed, one example of which includes a substrate upon which a lower mirror layer is formed. An active region and upper mirror layer are disposed, in that order, on the lower mirror layer. In particular, the upper mirror layer includes a plurality of DBR layers formed on the active region. The upper mirror layer additionally includes a photonic crystal formed on the plurality of DBR layers and having a periodic structure that contributes to the definition of a central defect. As a consequence of this structure, the photonic crystal has a reflectivity that is wavelength dependent, and the central defect enables the VCSEL to propagate a single mode.

摘要： A single mode high power vertical cavity surface emitting laser (VCSEL) using photonic crystals. A photonic crystal is included in at least one mirror layer of a VCSEL. The reflectivity of the photonic crystal is dependent on the wavelength and incident angle of the photons. The photonic crystal can be formed such that the VCSEL lases at a single mode. Because a single mode is generated, the aperture of the VCSEL can be enlarged to increase the power that is generated by the VCSEL for that mode. The photonic crystal can be used with or without DBR layers. The photonic crystal, in one example, forms an external cavity.

摘要： An optical apparatus in which multiplexed holograms are used to achieve wavelength selectivity and polarization manipulation is used to facilitate near-normal incidence of light on the holograms. The polarization manipulation allows light reflected from the holograms to be separated from the light incident on the holograms. In one application, the apparatus can be used to extract spectral lines of an analyte from radiation scattered from a sample.

摘要： This disclosure concerns systems, methods and devices for temperature-based control of laser performance. One example of a method is performed in connection with a laser of an optoelectronic transceiver. In particular, the laser is operated over a range of temperatures and the optical output of the laser is monitored. During operation of the laser, the bias current and current swing supplied to the laser are adjusted to the extent necessary to maintain a substantially constant optical output from the laser over the range of temperatures.

摘要： A temperature-controlled optoelectronic module that includes a module housing, a laser mount structure for affixing a laser package in the module housing, an optical fiber receptacle structure disposed adjacent to the laser mount structure, a thermal isolator affixed between the laser mount structure and the optical fiber receptacle structure, and a temperature controller coupled to the laser mount structure and operable to regulate temperature of the laser package is disclosed. In the absence of the thermal isolator, a “thermal short” may be created between the module housing and the laser package, substantially reducing the efficiency of the temperature controller. The presence of the thermal isolator eliminates the “thermal short,” substantially increases the effectiveness of the temperature controller and enables the miniaturization of temperature-controlled optoelectronic transceiver modules.

摘要： An edge emitting laser that emits a single mode using photonic mirrors. An edge emitting laser includes an active region that is formed between an n-type semiconductor material and a p-type semiconductor material. Photonic mirrors are formed in the laser to define a gain cavity and an external cavity. The gain cavity is bounded by a cleaved facet and a photonic mirror or by a pair of photonic mirrors. The external cavity is bounded by the photonic mirror of the gain cavity and either a cleaved facet or another photonic mirror. The mode emitted by the laser is determined by characteristics of the photonic mirrors, including the periodic cavity structures of the mirrors.
