“…Single wavelength operation in DM laser diodes is achieved by introducing index perturbations in the form of shallow-etched features, or slots, positioned at a number of sites distributed along the ridge waveguide as shown in Figure 16a [27][28][29][30][31][32]. The slots are realized using ICP dry etching, with a typical depth in the region of 1.5-2 μm and a width of $1 μm.…”

Low cost, compact and robust single mode semiconductor laser diodes emitting at λ $ 1.6-2.1 μm are highly desirable as light sources for trace gas spectroscopy and an increasing number of other applications, such as, high data-rate communications over hollow core photonic crystal fibre, noninvasive optical blood glucose monitoring. Indium phosphide based light sources provide a solid and flexible base for mid-infrared semiconductor diode lasers. This chapter provides an overview of the current state of the art in discrete mode InGaAs/InP long-wavelength quantum-well lasers emitting in the 1.6-2.1 μm wavelength range. The discrete mode laser is essentially a regrowth free modified ridge waveguide Fabry-Pérot laser whose optical spectrum has a single wavelength mode. High-performance and costeffective mid-infrared DM laser diode sources are well suited to a wide range of sensor applications. The current state of the art will also be outlined in this chapter.

“…The laser line width is less than 250 kHz, the SMRR is ∼40 dB, and the output power is about 4 mW. In 2018, the company [40] also reported a monolithic integrated single-mode red laser diode; for the diode, the laser wavelength is 689 nm, the laser power is 10 mW, the SMRR is 40 dB, the spectral line width is 2 MHz, and the mode-hopping-free output is guaranteed in the range of 0-50.…”

The era of smart travel has arrived, and the need for high precision lidar detection technology is increasing. With the advantages of high resolution, a strong anti-active jamming ability, small volume, light weight, and low cost, new solid-state lidars can meet the requirements of intelligent cars in the future. A narrow linewidth diode laser is an ideal light source of solid-state lidars. The progress and development of narrow linewidth diode laser techniques can greatly improve the application of solid-state lidars. In this paper, the technology and development is described in detail. In addition, the design ideas, key fabrication technologies, and optical characteristics of various narrow linewidth diode lasers are analyzed and discussed. Finally, the developments of narrow linewidth diode lasers are proposed.
