Push-Pull acousto-optic modulator based on non-suspended thin-film lithium niobate on silicon substrate
arXiv:2606.05337v1 Announce Type: new Abstract: Acousto-optic modulators (AOMs) are particularly attractive for microwave-to-optical conversion, quantum transduction, and optical frequency manipulation. For these applications, chip-scale AOMs that combine high efficiency, broad bandwidth, and low optical loss are highly desirable. Although suspended and resonant AOMs can enhance modulation efficiency, they typically suffer from stability concerns and limited bandwidth.
Long-term laser frequency stabilization with an FPGA-controlled scanning cavity
arXiv:2606.09720v1 Announce Type: new Abstract: We present an FPGA-based implementation of a scanning transfer cavity lock (STCL) for laser frequency stabilization, allowing for the simultaneous stabilization of multiple laser sources with respect to a single reference laser by means of a continuously scanned Fabry-Perot cavity. By exploiting the FPGA architecture to simultaneously perform cavity scanning, peak detection, and feedback actuation, we minimize latency and allow independent...
