Germanium window used in infrared detectors

Artificially designed microorganisms or cells carrying synthetic gene circuits can respond to disease markers or external signals, and realize the control of drug release location, release time, and release dose, which has gradually developed into a powerful weapon for humans to fight against diseases.

Germanium windows used in infrared thermal image

Most EML packages use gold wire bonding, and some use steps to reduce the length of gold wires, such as Huawei, Lumentum, etc., to increase bandwidth. Some of them use gold wires in parallel to reduce parasitic inductance and improve bandwidth, such as Broadcom. These have been written in too many articles in the collection, so I won't go into details. In this year's OFC, another company mentioned that NTT's Flip Chip flip-chip EML in 2021 can reduce the equivalent length of

Germanium windows used in Mid-wave infrared(MWIR) applications

Recently, on Xinhua Road, Korla City, Xinjiang Province, the reporter saw a smart gas laser inspection vehicle. Its model is an SUV, and the body is painted yellow. The location equipment has a built-in laser analyzer, which can quickly and effectively detect small leaks within a range of 100 meters. At the same time, combined with the GPS system and the latest intelligent platform software for quick display, you can have a panoramic view of whether there are leaks in the gas

Low-cost uncooled long-wave infrared continuous zoom optical design

Recently, a research team composed of South Korea's Asia University (Ajou University) and RayIR company successfully fabricated a PDMS substrate using double transfer technology combined with surface modification assisted bonding (SMB) Top-emitting 930 nm thin-film vertical-cavity surface-emitting laser (VCSEL). The threshold current of this thin-film VCSEL is as low as 1.08 mA at room temperature. When the injected current is 13.9 mA, its maximum output power is 7.52 mW. The

After the debut of the iPhone 14 series, the outside world began to shift their attention to the new generation of iPhone 15 series early on. Especially since this year, there have been a lot of revelations about the appearance and configuration of the phone. If there is no accident, the series will continue. Launched four models including iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Ultra, especially the two high-end versions have received a lot of exposure. Now th

NEC Corporation recently announced that it has successfully developed the world's first high-sensitivity uncooled infrared image sensor using high-purity semiconductor carbon nanotubes (CNTs). The sensor uses NEC's proprietary semiconductor CNT extraction technology, and NEC plans to realize the practical application of this uncooled infrared image sensor in 2025. Infrared image sensors convert infrared rays into electrical signals to obtain necessary information, so infrare

TRUMPF's goal is to manufacture short-wave infrared (SWIR) VCSELs using the most advanced mass production processes to achieve stable and reliable products with excellent performance. This revolutionary short-wave infrared VCSEL technology can help realize new applications such as mobile phone OLED under-screen sensors and automotive LiDAR. TRUMPF Photonic Components, a division of the TRUMPF Group, is a global leader in VCSEL and photodiode solutions and is mass producing SW

Optical metrology is one of the key technologies in manufacturing today. It can generally be defined as the science of making...

Visible light and short-wave infrared are currently more commonly used optoelectronic imaging bands. Short-wave infrared mainly comes from the infrared radiation in the reflection environment of ground objects and objects.

Narrow line-width lasers have extremely high spectral density, extremely low relative intensity noise and phase noise, and ultra-long coherence length.

Quantum magnetic detection sensors, or atomic magnetometers, are based on the principle of highly sensitive detection of weak magnetic fields by means of the interaction between lasers and atoms.

Recently, researchers at the National Institute of Standards and Technology (NIST) developed an on-chip system that can simultaneously...

VCSELs are used for sensing, such as lidar, and early applications used edge-emitting lasers for gesture recognition and somatosensory game sensors.

Recently, the application of the infrared temperature sensor on the range hood has appeared. Robam Appliances has brought a new product to the kitchen appliance market. The infrared sensor has a temperature measurement distance of 70 cm and is installed on the top side; the experience of fully automatic smoke control makes the People can't help but sigh "It turns out that the range hood can also be in harmony with my heart", making the user's cooking life more convenient, he

TDLAS technology is mainly divided into direct absorption spectroscopy (Direct Absorption, DA) and wavelength modulation spectroscopy (Wavelength Modulation Spectroscopy, WMS).
