Description
This poster presents the design of a multi-band, low-noise transimpedance amplifier for balanced homodyne detection in optical squeezing experiments. To facilitate comprehensive real-time system diagnostics, the architecture provides simultaneous readout across four distinct spectral channels: a DC path for local oscillator power monitoring, a high-gain “audio-band” (100 Hz – 100 kHz) sum and difference output for technical noise and vibration analysis, and a radio-frequency difference output (5 MHz – 400 MHz) for quantum state measurement.
