Amplitude-type liquid crystal spatial light modulator
We present an innovative electrode-free Thermo-Optically-Addressed SLM (TOA-SLM) which relies on the thermotropic properties of liquid crystals : the absorption of a writing beam modifies the local temperature, and hence the liquid crystal birefringence. A large-area liquid-crystal spatial light modulator for amplitude modulation of high-energy infrared laser beams. SPIE Organic Photonics + Electronics, 2025, Aug 2025, San Diego, United States. ⟨hal-05293745⟩ HAL is a multi-disciplinary open access archive for the. Spatial light modulators, as dynamic flat-panel optical devices, have witnessed rapid development over the past two decades, concomitant with the advancements in micro- and opto-electronic integration technology. A simple example is an overhead projector transparency. This phase control is highly stable with minimal fluctuations and minimal crosstalk with.

Silicon Photonics Liquid Cooling Technology
Silicon Photonics + Liquid Cooling: Silicon photonics (SiPh) reduces power consumption of optical modules. Leading manufacturers at home and abroad are continuously investing in this technology, while announcements and standards. Traditional air-cooling solutions can no longer meet the thermal demands of high-performance chips such as GPUs, ASICs, and optical chips. According to IDC, the global liquid-cooled data center market will exceed USD 20 billion by 2027, with a compound annual growth rate (CAGR) of 25%. Replacing pluggable transceivers with silicon photonics on the same package as the ASIC, NVIDIA CPO innovations provide 5x better power. One of the most effective emerging solutions is direct-to-chip liquid cooling, which supports AI workloads cooling by delivering efficient heat management while enhancing sustainability and performance. ASIC Race: GPUs will remain the dominant force, growing fastest due to the complexity and rising compute demands of AI-intensive workloads. Modern AI workloads—especially those involving generative models and machine.
