“…Then the same setup was used to register the light emission at the lasing frequency when the pump was applied. On the other hand, a vertical coupling configuration that features a microdisk or an array of microdisks located on top of the buried optical waveguide has been successfully demonstrated (Tishinin 1999;Little et al 1999;Klunder et al 2001;Djordjev et al 2002;Choi et al 2004).…”

Research into microdisk lasers demonstrates new achievements both in the technology and in the associated physical effects and applications. Melting and rounding of the disk edge boosts the Q-factors due to improved surface smoothness. In-plane cavity shape is widely used as a design instrument. Optimal shaping of pumped area lowers the threshold power. Photonic molecules made of several microdisks as "photonic atoms" show lasing at several closely spaced frequencies. A microdisk with a single quantum dot as an active region is considered as the most promising system for realisation of a single photon emitter necessary for quantum computing. These new effects and devices can be simulated with accurate numerical techniques, developed recently for "warm-cavity" linear modelling, that are able to bring a new vision of the physics of lasing.

“…Then, the cured polyimide patterns having nearly the same radii as the disks are used as the openings for the electrodes, which is favorable for efficient carrier injection into the disk periphery region but very difficult to achieve when a conventional photolithographic alignment technique is used. Details on further processes can be found in [4]- [8]. Fig.…”

“…Moreover, active microdisks take full advantage of the versatile functionalities offered by microresonators. By implementing active materials into the microdisk, we have demonstrated tunable filters [4], gain and electroabsorption trimming modulators [5], [6], and continuous-wave bus-coupled microdisk lasers [7], [8].…”

Abstract-We demonstrate a 1.6-nm spectrally spaced eight-channel demultiplexer using active semiconductor microdisk resonators as a platform technology. Taking full advantage of the active microdisks, we are able to switch ON and OFF a resonator individually and tune the resonant wavelength as well by controlling the current injection levels. The use of active microdisks affords narrow spectral linewidth ( 0.15 nm), low insertion loss ( 2.5 dB), and distinct channel isolation ( 15 dB) for the demultiplexed output signals.

“…Recently, we demonstrated electrically injected laser operation for an InP-based microdisk laser integrated with and coupled to a nanophotonic silicon-on-insulator (SOI) wire waveguide [4]. Since the lasing wavelength of a microdisk laser is fixed through its diameter, they are attractive candidates as single-mode lasers for applications requiring wavelength-division multiplexing [5]. Here, we report on a compact, silicon-integrated multiwavelength laser (MWL) source based on an array of such waveguide-coupled microdisk lasers.…”

Abstract-We report on the performance of a compact multiwavelength laser (MWL) source heterogeneously integrated with and coupled to a silicon-on-insulator (SOI) waveguide circuit. The MWL consists of four InP-based microdisk lasers, coupled to a common SOI wire waveguide. The microdisk lasers operate in continuous-wave regime at room temperature, with a threshold current around 0.9 mA and a waveguide-coupled slope efficiency of up to 8 W/mA, for a microdisk diameter of 7.5 m. The output spectrum contains four laser peaks uniformly distributed within the free-spectral range of a single microdisk. While thermal crosstalk is negligible, laser peak output powers vary up to 8 dB for equal microdisk drive currents, as a result of loss due to coupling with higher order modes supported by the 1-m-thick microdisks. This nonuniformity could be eliminated by reducing the microdisk thickness.Index Terms-Heterogeneous integration, microdisk laser, multiwavelength laser source, silicon photonics.
