... peak wavelength of 1877 nm is demonstrated, with a side mode suppression ratio (SMSR) of $45 dB achieved, in excellent agreement with simulated values. In Figure 21a we plot the peak wavelength versus bias current as a function of laser submount temperature. The peak wavelength tunes linearly with bias current at a tuning rate of $0.017 nm/mA. ...

... peak wavelength tunes linearly with bias current at a tuning rate of $0.017 nm/mA. In Figure 21b the optical emission spectrum over a wide temperature range, from À5 to 55°C, is plotted. The single mode peak lasing wavelength shows a linear dependence with current and temperature, with a tuning rate of Δλ/ΔI $0.017 nm/mA and Δλ/ΔT of 0.113 nm/ o C, consistent with that expected due to the temperature-induced change in the refractive index [29]. ...

... A simple and effective alternative approach to achieve single-mode laser is introducing micronlevel index perturbations into the ridge waveguide which can be easily prepared by standard contacted photolithography [15]. Significant progress has been achieved in InP-based lasers in the near infrared region [16], proving that this approach not only has a simple and low-cost fabrication process but also portrays lots of superiorities over the DFB and DBR lasers with stable operation over a larger temperature range, narrow linewidth and low sensitivity to optical feedback [17,18]. Moreover, the convenience of monolithic integration with other electro-optical modulators [19][20][21], enables this kind of laser an ideal candidate for photoelectric integrated devices. ...
In this paper, we put up a robust design of a stable single-mode-operated GaSb-based laser diode emitting around 1950nm. This novel design structure with socketed ridge-waveguide enables a simple fabrication and batch production of mid-infrared laser diodes on account of the mere usage of standard photolithography. By introducing micron-level index perturbations distributed along the ridge waveguide, the threshold gains of different FP modes are modulated. Four geometrical parameters of the perturbations are systematically optimized by analyzing the reflection spectrum to get a robust single-mode characteristic. Based on the optimized geometrical parameters, 1-mm long uncoated lasers are carried out and exhibit a stable single longitudinal mode from 10 °C to 40 °C with a maximum output power of more than 10 mW. Thus, we prove the feasibility of the standard photolithography to manufacture the monolithic single-mode infrared laser source without regrowth process or nanoscale lithography.
This article proposes an electrothermal three-degrees-of-freedom (3-DOF) micro-positioner equipped with a waveguide path, which can potentially be used for chip-to-chip alignment in photonic integrated circuits. The micro-positioner provides translational displacements along the x-, y-and z-axes with manageable levels of cross-sensitivity between axes. A fabricated prototype provides displacements of

Heterogeneous integration of InP and GaSb on Si substrates holds a huge potential interest in near-infrared and mid-infrared optoelectronic devices. In this study, 2-inch 180-nm-thick InP and 185-nm-thick GaSb thin layers were successfully transferred onto the Si substrates to form high-quality and ultra-smooth InP/Si and GaSb/Si templates using molecular beam epitaxy (MBE) and the ion-slicing technique together with selective chemical etching. The relocation of the implantation-introduced damage in the sacrificial layer enables the transfer of relatively defect-free InP and GaSb thin films. The sacrificial layers were completely etched off by selective chemical etching, leaving ultra-smooth epitaxial surfaces with a roughness of 0.2 nm for the InP/Si template and 0.9 nm for the GaSb/Si template, respectively. Thus, the chemical mechanical polishing (CMP) process was not required to smooth the surface which usually introduces particles and chemical contaminations on the transferred templates. Furthermore, the donor substrate is not consumed and can be recycled to reduce the cost, which provides a paradigm for the sustainable and economic development of the Si integration platform.
In recent years, applications of mid-infrared radiation have proliferated tremendously, resulting in an ever-growing search for suitable laser sources that can directly provide the few-cycle pulses needed for efficient downstream MIR generation. To achieve the high sensitivity and specificity required for the spectroscopic investigation of (bio-)molecular samples in the MIR fingerprint region, sophisticated detection schemes such as electro-optic sampling (EOS) have to be combined with ultrafast laser technology to detect subtle changes encoded in the mid-infrared electro-magnetic waveform. However, the probe pulse duration in EOS-based measurements is a critical parameter since it limits the temporal resolution and thus the spectral bandwidth that can be measured at high frequencies. Therefore, ultrashort probe pulses are highly sought after to increase the detection bandwidth. Moreover, if few-cycle laser pulses can be directly generated in the short-wave mid-infrared region at around 2–3 µm, the conversion efficiency for frequency downconversion into the long-wavelength MIR beyond 3 µm is significantly improved, while a broader selection of suitable nonlinear crystals is available also.
