Giant gain enhancement in photonic crystals with a degenerate band edge

We propose a new approach leading to giant gain enhancement. It is based on unconventional slow wave resonance associated to a degenerate band edge (DBE) in the dispersion diagram for a special class of photonic crystals supporting two modes at each frequency. We show that the gain enhancement in a Fabry-Pérot cavity (FPC) when operating at the DBE is several orders of magnitude stronger when compared to a cavity of the same length made of a standard photonic crystal with a regular band edge (RBE). The giant gain condition is explained by a significant increase in the photon lifetime and in the local density of states. We have demonstrated the existence of DBE operated special cavities that provide for superior gain conditions for solid-state lasers, quantum cascade lasers, traveling wave tubes, and distributed solid state amplifiers. We also report the possibility to achieve low-threshold lasing in FPC with DBE compared to RBEbased lasers.

“…PhCs have many attractive characteristics such as photonic bandgap (PBG), localization effect, and refraction effect. By introducing point defect and/or line defect, PhC-based devices can be made [2], such as PhC-based waveguide [3][4][5], nanocavity [6][7][8], low threshold lasers [9][10][11][12], PhC-based filter [13][14][15], PhC fibers [16][17][18][19], optical sensors, and so on.…”

A high sensitivity pressure sensor based on two-dimensional photonic crystal

Abstract:In this paper, we propose and simulate a pressure sensor based on two-dimensional photonic crystal with the high quality factor and sensitivity. The sensor is formed by the coupling of two photonic crystal based waveguides and one nanocavity. The photonic crystal with the triangular lattice is composed of GaAs rods. The detailed structures of the waveguides and nanocavity are optimized to achieve better quality factor and sensitivity of the sensor. For the optimized structures, the resonant wavelength of the sensor has a linear redshift as increasing the applied pressure in the range of 0 -2 GPa, and the quality factor keeps unchanged nearly. The optimized quality factor is around 1500, and the sensitivity is up to 13.9 nm/GPa.

“…Compared to conventional Fabry-Perot or DFB edge-emitting lasers, such micro cavity lasers have many interesting characteristics, such as ultra-small size, with the possibility of close-to-diffraction-limited mode volume, ultra-low threshold, and on-chip integration [11][12][13][14][15]. However, because the semiconductor membrane has a thickness of a few hundred nanometers and normally is suspended in air, heat generated through the pumping process, either optical or electrical, may accumulate in the structure, making it difficult to achieve continuous-wave (CW) lasing at room temperature [11][12][13][14]. Even with the achievement of CW lasing, the laser output power saturates when the pump power is only a few times larger than the laser threshold level [16].…”

Abstract:We report a systematic study of thermal effects in photonic crystal membrane lasers based on line-defect cavities. Two material platforms, InGaAsP and InP, are investigated experimentally and numerically. Lasers with quantum dot layers embedded in an InP membrane exhibit lasing at room temperature under CW optical pumping, whereas InGaAsP membranes only lase under pulsed conditions. By varying the duty cycle of the pump beam, we quantify the heating induced by optical pumping in the two material platforms and compare their thermal properties. Full 3D finite element simulations show the spatial temperature profile and are in good agreement with the experimental results concerning the thermal tolerance of the two platforms.
