| contents | Precisely stabilizing laser frequency is crucial for advancing laser technology and unlocking the full potential of various quantum technologies. Here, we propose a compact device for stabilizing frequency of a semiconductor laser through mode coupling effects, which provides enhanced sensitivity. Our proposed architecture features a main ridge waveguide with a Bragg grating, flanked by two curved ridge waveguides. This configuration exhibits an optical phenomenon characterized by a transmission crossing at the wavelength of the Bragg grating. Using particle swarm optimization strategy and employing efficient figures of merit, we achieve a high transmission crossing. The observed asymmetric transmission crossing not only holds the promise for an efficient and compact on-chip laser frequency stabilizer, but also fosters the development of novel sensing platforms with heightened sensitivity. |
