penalty of a weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) upstream transmitter are investigated. By fixing the downstream power at -13 dBm, the downstream ASE data is amplitude-squeezed by ...

In one device, photothermal microcavities simultaneously measure light power and wavelength for potential applications in ...

Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control ...

The innovative 3D micro-printed microlaser sensor demonstrates exceptional sensitivity, paving the way for advanced lab-on-a-chip diagnostic applications.

Abstract: The circuit properties of a resonant cavity are effectively described by its loaded Q, unloaded Q, and shunt resistance. One method of Q measurement depends on an accurate knowledge of the ...
