By using standard lithography techniques, selective area epitaxy of quantum dots was achieved on In/sub 0.20/Ga/sub 0.80/As layers with a QD density exceeding 3/spl times/10/sup 10/ cm/sup 2/. The advantage of this method lies in the lack of oxide or nitride mask material, allowing for a single regrowth process that is not complicated by any additional thermal dose or growth rate enhancement.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

A similar situation was observed for the lateral VCSEL mode for a very small aperture oxide-define waveguide structure. A narrow-waveguide VCSEL design incorporating a separate current confinement aperture is shown schematically. This design then allows one to adjust the optical overlap with the gain region by choosing the current aperture. The device is fabricated by two-step MOCVD growth.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

We demonstrate high Q vertically coupled passive microdisk resonators based on the InP material system as a first step towards utilizing active devices, and to understand the parameters limiting their performance. Vertical coupling is chosen because it exhibits two major advantages compared to the lateral geometry, namely: i) precise control of the coupling coefficient by epitaxial growth; ii) the material composition of the waveguides and resonator can be optimized and grown independently, which facilitates the design of active microdisk devices - ON/OFF switches, modulators and microdisk lasers.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.
