Modulation-Free Laser Stabilization with Extended Locking Range on a SiN Chip

TL;DR

This paper presents a modulation-free laser stabilization system on a SiN chip that significantly extends locking range and suppresses noise, enhancing laser stability without the need for modulation techniques.

Contribution

The work introduces a novel modulation-free stabilization method using a cavity-coupled MZI on a SiN chip, achieving large locking range and high noise suppression.

Findings

Over 36 dB noise suppression achieved

More than tenfold increase in locking range

Successful demonstration on a low-loss SiN chip

Abstract

We demonstrate a modulation-free laser stabilization system using a cavity-coupled MZI with aided acquisition on a low-loss SiN chip, achieving more than an order-of-magnitude improvement in locking range and over 36 dB noise suppression.
