Abstract:
The facet heating of high-power laser diodes significantly influences device reliability. To mitigate facet temperature, current blocking (CB) regions are employed at both cavity facets of the laser. In this paper, we investigate the device characteristics of uncooled InGaAlAs lasers with CB facets. We observe two types of light versus current (LI) curves and propose corresponding physical models. Our findings demonstrate the high reliability performance of uncooled lasers with proper engineering design and CB process.

Abstract:
Semiconductor laser diodes are important components for fifth-generation wireless technologies. To meet 5G wireless specifications, ever increasing performance and reliability requirements of each component become necessary to guarantee uptime air service. In this paper, we present highly reliable 25G DFB uncooled lasers that exhibit low threshold current, high single-mode, high bandwidth, and excellent eye pattern for uncooled operations of -40 to 85°C. Ultra-high component reliability is demonstrated to ensure stable operations for 5G mobile communications.

Abstract In work, the possibilities of using uncooled and cooled optical elements (including laser passive and deformable mirrors) with an increase in the power of laser facilities are analyzed. To increase the permissible light loads acting on the optical elements, the use of highly efficient cooling systems with minichannels (coplanar and multi-tiered), providing a high compactness of the heat exchange surface and the intensification of heat transfer, is considered. The advantages and efficiency of the proposed cooling systems for reducing the displacement of the optical surface of the mirro

This thesis investigates different material systems and processing technology for high temperature compatible laser diodes used in volume applications within the 1.3-μm telecom wavelength window. Laser diodes built from such materials are much desired in order to eleminate the need for active temperature control needed in current systems, which significantly increases both complexity, size and cost. The structures were grown by Metal-Organic Chemical Vapor Deposition (MOCVD) and the evaluation of materials was performed using different characterization methods such as High-Resolution X-Ray Dif

Abstract:
An optical beamforming network that uses an uncooled Fabry-Perot laser is demonstrated. This is achieved by using a fast-scanning, high-resolution optical spectrum analyzer to track the frequency and power shift of the uncooled laser, and then reconfiguring a programmable Fourier-domain optical processor to provide compensation. In this way, the need for temperature control of the laser is eliminated, and the number of optical sources is reduced by using the output spectral lines of the laser. The system realizes six wideband microwave photonic phase shifters, and the resulting magnitude and p

Traditionally, for high-speed operation in long-distance transmission, DFB lasers are usually adopted for their superior output performance. However, the demand of second epitaxial regrowth will induce the complicated process and lower yield. The DFB laser also usually needs an additional optical isolator to avoid reflective light. These reasons lead to the cost of the module for the DFB laser is essentially high. D

Abstract:
An uncooled laser transmitter is cheaper and more reliable than a thermo-electrically cooled laser transmitter because of its simplicity in packaging. A low-cost, highly-reliable uncooled laser may have a strong influence on pushing fiber deployment closer to the home. For loop applications, the laser transmitter must operate reliably over the temperature range from -40 to 85°C. It is rather difficult to make high performance uncooled lasers in the long wavelength region (1.3-1.55 μm) using the conventional GaxIn1-xASyP1-y/InP materials system because the laser temperature performance suffers
