“…An exception is the slotted laser reported in [6][7][8][9][10][11][12][13]. These lasers use optical defects in a standard Fabry-Pérot (FP) laser to specifically select a single mode, and such optical defects are formed by etching around 1 µm wide slots into the top ridge of the laser waveguide.…”

“…These slots, if we consider them as a kind of grating, are generally very high order surface gratings. Up to now there have been two types of laser schemes based on these slots: one is the mode selective FP laser type [6][7][8][9][10][11], where the slots are seated inside the laser cavity. This type of laser needs two cleaved facets to form the fundamental FP cavity and uses the slots to select one single mode from the multiple modes of the FP cavity.…”

Abstract:The re-growth free single mode lasers based on etched slots suitable for photonic integration are presented in this paper. The fabricated 650µm long laser exhibits a threshold current and a slope efficiency of about 32mA and 0.12mW/mA, respectively. The stable single mode operation has been observed with a side mode suppression ratio (SMSR) over 50dB at a current injection of 100mA for the fabricated laser. Such a laser integrated with electroabsorption (EA) modulator is also demonstrated. The integrated device has an extinction ratio over 10 dB at 2.2V driving voltage with the lasing wavelength of around 20nm positive detuning relative to the gain peak. The bandwidth measured is about 3GHz for the integrated device. 326-335 (1996). ©2011 Optical Society of America

“…By judicious placement of a sequence of low-loss slots with respect to the facets, preselected FP modes could be significantly enhanced leading to robust single-frequency lasing with wide temperature stability [10], [11] as well as tuning with fast switching characteristics [12]. More recently, we have characterized the properties of slots that are etched more deeply, namely, to the depth of, but not through, the core waveguide containing the quantum wells [13].…”

Abstract-A sequence of partially reflective slots etched into an active ridge waveguide of a 1.5 µm laser structure is found to provide sufficient reflection for lasing. Mirrors based on these reflectors have strong spectral dependence. Two such active mirrors together with an active central section are combined in a Vernier configuration to demonstrate a tunable laser exhibiting 11 discrete modes over a 30 nm tuning range with mode spacing around 400 GHz and side-mode suppression ratio larger than 30 dB. The individual modes can be continuously tuned by up to 1.1 nm by carrier injection and by over 2 nm using thermal effects. These mirrors are suitable as a platform for integration of other optical functions with the laser. This is demonstrated by monolithically integrating a semiconductor optical amplifier with the laser resulting in a maximum channel power of 14.2 dBm from the discrete modes.

“…Discrete Mode laser diodes (DMLDs) [2] are simple, regrowth-free ridge waveguide Fabry-Pérot (FP) lasers. Single wavelength operation in DMLDs is achieved by introducing index perturbations in the form of etched features positioned at a small number of sites distributed along the ridge waveguide …”
