https://www.electronics-lab.com/vishay-vcnt2025x01-reflective-optical-sensor/
Vishay VCNT2025X01 Reflective Optical Sensor is a reflective sensor in a miniature SMD package. It has a compact construction where the emitting light source and the detector are arranged in the same plane. The operating infrared wavelength is 940nm. The detector consists of a silicon phototransistor. The sensor analog output signal (photocurrent) is triggered by […]

Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability and a linear contact. No output power supply is required.

Record-setting flexible phototransistor revealed
https://www.electronics-lab.com/record-setting-flexible-phototransistor-revealed/
Researchers at the University of Wisconsin-Madison have revealed a unique phototransistor that is flexible and faster and more responsive than any similar phototransistor. The innovative phototransistor could improve the performance of myriad products — ranging from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites — that rely on electronic light sensors. Integrated […]
