Cold-cavity measurement of optical loss from oxide-confined vertical-cavity surface-emitting lasers
نویسندگان
چکیده
Microcavity laser design and performance optimization requires a quantitative knowledge of the cavity optical losses. A generalized method using sub-threshold spectral measurements matched to model calculations is demonstrated to determine optical loss in microcavity lasers. Cold-cavity spectral characteristics are used to extract the size-dependent optical loss for small diameter oxide-confined vertical-cavity surface emitting lasers. For oxide aperture diameters less than 4 lm, the oxide scattering loss can be greater than 10 cm , similar to the typical values of free carrier absorption loss. VC 2014 AIP Publishing LLC.

Spontaneous emission factor in oxide confined vertical-cavity lasers
We report on measurements of the spontaneous emission factor for oxide-confined InGaAs vertical cavity surface emitting lasers. The spontaneous emission factor is determined as a function of the active layer volume from the measurement of small-signal harmonic distortion at threshold. For a 333 mm oxide aperture device we obtain spontaneous emission factor of 4.2•10 at room temperature. © 1997 ...
متن کاملSurface-structure-assisted chaotic mode lasing in vertical cavity surface emitting lasers.
We demonstrate chaotic mode lasing in vertical cavity surface emitting lasers at room temperature, with an open cavity confined laterally by the native oxide layer. Instead of introducing any defect mode, we show that suppression of lower-order cavity modes can be achieved by destroying vertical reflectors with a surface microstructure. Lasing on chaotic modes is observed directly through colle...
متن کاملDifferential carrier lifetime in oxide-confined vertical cavity lasers obtained from electrical impedance measurements
Differential carrier lifetime measurements were performed on index-guided oxide-confined vertical cavity surface emitting lasers operating at 980 nm. Lifetimes were extracted from laser impedance measurements at subthreshold currents, with device size as a parameter, using a simple small-signal model. The carrier lifetimes ranged from 21 ns at 9 mA, to about 1 ns at a bias close to threshold. F...
متن کاملObservation of low-frequency fluctuations in vertical-cavity surface-emitting lasers.
Low-frequency fluctuations, which are typical irregular oscillations in edge-emitting semiconductor lasers, are experimentally observed for the y-polarization mode (y is the direction along the optical axis of a laser material) in a vertical-cavity surface-emitting laser with optical feedback.
