The common-emitter amplifier circuit generates an output which transitions from a high state to a low state when light in the near-infrared range is detected by the phototransistor. The wavelength ...

A single phototransistor mimics retinal bipolar cell function while detecting visible and infrared light, enabling low-power image processing through programmable ON and OFF photoresponses. (Nanowerk ...

Stratos Optical Technologies now offers increased packaging density as a custom manufacturing option for its optical flex circuit products (see figure). The new optical flex circuit design is called ...

The library of two-dimensional (2D) layered materials keeps growing, from basic 2D materials to metal chalcogenides. Unlike their bulk counterparts, 2D layered materials possess novel features that ...
