At OFC 2024, several companies showcased a variety of LPO modules and delivered presentations on this topic at the forum. Lightcounting has provided insights into market trends for high-speed optical modules, and some companies have referenced this data to suggest that LPO modules will become a critical low-power, low-latency option for AI applications in the 800G (and future 1.6T) pluggable optical module market, as well as in the 400G and above AOC market. Below are the dem

The working principle of quantum well infrared detectors is based on subband transitions. After absorbing infrared radiation, the detector excites electrons in the quantum well, causing them to transition from the ground state to the continuum state, thereby achieving infrared detection. According to a report by MMS Consultancy, a recent research team from Shanghai University of Technology and the Shanghai Institute of Technical Physics, Chinese Academy of Sciences, published

The integration of SOA is approached from three aspects: How to increase output power. How to reduce the impact of facet reflection. How to reduce noise and improve signal (eye diagram) modulation quality.

VCSEL, Vertical-Cavity Surface-Emitting Laser, referred to as Vertical Cavity Surface-Emitting Laser, is a semiconductor laser that emits laser light perpendicular to the substrate surface.

Using TriEye's proprietary depth algorithm, SEDAR technology generates point clouds that are calculated pixel by pixel using a pulsed lighting method.

In the past few years, the rapid growth of the information age has captured global attention, particularly regarding the Internet of Things (IoT), artificial intelligence (AI), big data, and cloud computing. Among these technological advancements, smart gas sensors have emerged as a significant interface for human-machine interaction (HMI) and a crucial tool for interacting with the external environment. When using a gas sensor as an HMI interface, it is crucial for it to be

Infrared dual-band photodetector is an important multi-spectral detector, especially in the near infrared/short-wave infrared region, which has stronger penetration ability than visible light, and can identify cold background objects with lower loss than mid-wave infrared, so it is widely used in civil and military fields.

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

Let's see the classification of the VCSEL: Edge-Emitting Laser (EEL) and Surface-Emitting Laser(SEL) Edge-Emitting Laser (EEL) and Surface-Emitting Laser(SEL) The low cost of VCSEL is mainly reflected in the fact that the light-emitting area does not need to be directly touched by external technology, and the side emitting side needs to be etched or cleaved, and it needs to be coated. These processes have a huge risk of failure. The second factor is that the GaAs wafer used

G.654 optical fiber is usually designed for C-band transmission. The cut-off wavelength defined by the specification is 1530nm. The cut-off wavelength means that > this wavelength, the fiber is transmitted in single mode, and below this wavelength, the fiber is transmitted in this fiber. It is not guaranteed to be a single mode, and generally high-order modes will be excited.
