Optical balanced detection
WebOct 13, 2024 · Balanced detection is a popular method to cancel out the effect of laser intensity noise in optical measurements and spectroscopy. However, the signal-to-noise ratio (SNR) that can be achieved with balanced detection is constrained by the standard quantum limit (SQL). Here, we propose quantum-enhanced balanced detection (QBD), … Weba tail current source connected to a common node, the tail current source configured to source a predetermined current; a plurality of high-amplitude detection branches connected to the common node, each of the plurality of high-amplitude detection branches having an input node configured to receive via a multi-wire bus a respective element of a balanced …
