Uncooled infrared focal plane array (IRFPA) is the core component of uncooled infrared detectors , which can be subdivided according to different detection mechanisms: thermistor type, pyroelectric type, thermopile type, diode type, field effect tube type, Optomechanical type etc. Among them, the diode-type IRFPA is conducive to achieving high array uniformity and high spatial resolution because the manufacturing process is compatible with the complementary metal-oxide-semico

In recent years, the rapid development of synthetic biology has brought new opportunities for the in-depth optimization of tumor bacterial therapy. Based on synthetic biology methods, scientists can use genetically engineered microorganisms or cells instead of traditional chemical small molecules or biological agents as the basis for the development of new disease treatments. Artificially designed microorganisms or cells carrying synthetic gene circuits can respond to disease

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

The capability of certain animals to change appearance serves multiple functions in physiological behaviors such as predation and self-preservation. This ability has fascinated humans for centuries and inspired the development of camouflage materials and devices. Currently, materials such as plasmonic nanodot arrays, responsive photonic crystals, and multilayer thermo-chromic liquid crystals have been designed to selectively reflect light in the visible spectrum to change its

Integrated mid-infrared dual-comb system based on dual-wavelength lasers

43GHz EML (Electro-absorption Modulated Laser)

This TO can is obliquely posted because two of the four wavelengths are 1270 nm and 1310 nm, which are very close. A filter with a small angle is required to effectively separate the two wave fields.

How to reduce the power consumption of 1.6T optical module. 1.6T adopts single-wave 200G optical technology, and the electrical signal may have a short-term gearbox for transition.

RIN is relative intensity noise, that is, noise relative to the strength of the signal. Noise is defined as uncertainty in magnitude of deviation from ideal.

An optical module is a component in the fiber optic communication link, with fiber optic being the main component of fiber optic communication. Before discussing optical modules, let's first talk about fiber optics.

The ONU receiver's bit rate is 10Gbps, and its working bandwidth is 7-8GHz, which is close to the working frequency of wifi and can cause interference. The power of wifi is much stronger.

InnoLight has launched a high-power anti-reflection laser. InnoLight's CW high-power laser chip can reach 100mW optical power. We put InnoLight’s lasers and other peers’ lasers into the same coordinate system for comparison as shown in the figure below. The PI curve given by InnoLight is the data at 25°C. According to this data, the electro-optical efficiency of the linear segment is about 29%, the efficiency of the two Lumentum designs at room temperature is about 40%, and t

Nitrogen is most commonly used in the packaging process of optical devices. Another common gas is helium, which is used to work with nitrogen.

The electrostatic force-based VOA mirror adjustment can be applied in 100G DR4 40km applications to cooperate with SOA for signal amplification at the receiver end.

TO is made as a flat window for hermetic protection. In addition, a lens is added near the core for focusing.

To improve coupling efficiency and create more parallel light, a combination of two lenses is required. The collimator lens converts the divergent light of the laser. The size of the parallel light spot is related to the distance between the lens and the chips.
