VCSELs and How to Keep Them Cool

Vertical-cavity surface-emitting lasers (VCSELs) are a type of semiconductor laser that emits a circular, low-divergence beam of light perpendicular to the surface of the chip, as opposed to edge-emitting lasers that emit parallel to the chip surface. This beam quality simplifies optical system design and improves coupling efficiency. VCSELs are characterized by their unique structure, which consists of a thin layer of active semiconductor material sandwiched between two highly reflective mirrors.

Reliable Solid-State Environmentally Friendly Thermoelectric Assemblies

Thermoelectric cooler assemblies (TEAs) offer benefits such as precise temperature control, compact size, quiet operation, and the absence of refrigerants or moving parts. Some may argue that they have limitations in terms of cooling capacity and efficiency compared to traditional refrigeration methods, however, we can demonstrate otherwise.

Eco-Friendly Temperature Stabilization Solutions for OEMs’ Climate Action Goals

Introduction

At Tark Thermal Solutions, we are committed to eco-friendly solutions for temperature stabilization for demanding applications across global medical, analytical, industrial, transportation, and telecommunications markets.

Older compressor-based systems often use high global-warming potential (GWP) HFC refrigerants like R134a and R404A. New industry requirements are moving away from the use of such refrigerants due to their environmental impact. New government restrictions on traditional and natural refrigerants are central to compressor-based systems.

Heating and Cooling of Incubator Chambers

Introduction

Incubators, used for cell and tissue cultivation in hospital and laboratory settings, grow and maintain cell and tissue samples under controlled conditions for hours, weeks, or even months. They create the ideal environment for cell and tissue sample growth by maintaining optimum levels for temperature, humidity, carbon dioxide, and oxygen. Precision control of these factors enables research and experimental work in industries where cell culture is vital, such as zoology, microbiology, pharmaceutical research, food science, and cosmetics. 

Common Coolant Types and their Uses in Liquid Cooling Systems

Introduction

As power densities and thermal loads continue to increase in crowded electronic systems, and specific analytical and diagnostic testing processes demand more temperature stabilization for improved accuracy and results, more equipment designers, R&D labs and diagnostic laboratories are turning to liquid cooling solutions for better thermal management. Optimal cooling fluids improve accuracy of results, improve equipment performance, minimize downtime, reduce maintenance costs, ensure safety and can help meet environmental compliance.

Multistage Micro Thermoelectric Coolers for Miniature Optical Image Sensing Applications

Introduction

Miniature optical packages provide a robust hermetic seal to protect small image-sensing components, including CMOS, CCD, IR, and X-ray detectors. Optical packages, like Transistor Outline (TO) Cans, are widely used for image-sensing applications. For high-end image sensing, micro thermoelectric coolers (TECs) can be integrated into optical packages called Optical Thermoelectric Assemblies (TEAs). This will provide deep cooling to temperatures well below ambient to minimize thermal noise and capture maximum light spectrum.

Advanced Liquid Cooling for Rheometers

 

Introduction

Rheometers are scientific instruments used for studying the stress-strain relationship of polymers, fluids, and other soft materials to understand their flow/deformation properties. Rheometers are applied in a wide range of applications, such as in the development of new materials, quality control, and process optimization. Any rheometer that operates at elevated temperatures or measures temperature-dependent material properties requires a cooling system to maintain a precise temperature during testing.

Ultra-Compact Coolers for Next-Generation Optical Transceivers

Introduction

Fiber optic technology has essentially replaced copper wire in datacom and telecommunication industries. Emerging applications, including artificial intelligence and machine learning, require higher data transfer speeds and bandwidth across significant distances all at a lower cost. In many applications, temperature stabilization improves the performance and longevity of critical optoelectronic components vital in fiber optic systems.
