摘要:

高相干可见光和近可见光激光源对于先进的定位/导航/定时系统以及经典/量子传感系统的操作至关重要。然而,这些台式激光器的复杂性和尺寸是其在实验室之外过渡的障碍。在这里,一个系统上的一个芯片,发射高相干可见光和近可见光波被证明。该器件依赖于一种新的方法,其中通过自注入锁定的波长转换和相干性增加被组合在单个非线性谐振器内。这种简化的方法在混合集成器件中得到了验证,并提供了约10-30 kHz的短期线宽。片上,转换后的光功率超过2毫瓦也得到了。测试结果表明,异质集成可以获得25%以上的转换效率,输出功率超过11 mW。由于该方法使用成熟的III-V族泵浦激光器与薄膜锂酸盐相结合,因此可以扩展用于高相干可见光发射器的低成本制造。此外,相干产生处理可以转移到包括光学参量振荡、和/差频产生和三次谐波产生的其它频率转换处理。

英文摘要:

High coherence visible and near-visible laser sources are centrally important to the operation of advanced position/navigation/timing systems as well as classical/quantum sensing systems. However, the complexity and size of these bench-top lasers is an impediment to their transitioning beyond the laboratory. Here, a system-on-a-chip that emits high-coherence visible and near-visible lightwaves is demonstrated. The devices rely upon a new approach wherein wavelength conversion and coherence increase by self-injection-locking are combined within in a single nonlinear resonator. This simplified approach is demonstrated in a hybridly-integrated device and provides a short-term linewidth around 10-30 kHz. On-chip, converted optical power over 2 mW is also obtained. Moreover, measurements show that heterogeneous integration can result in conversion efficiency higher than 25% with output power over 11 mW. Because the approach uses mature III-V pump lasers in combination with thin-film lithium niobate, it can be scaled for low-cost manufacturing of high-coherence visible emitters. Also, the coherence generation process can be transferred to other frequency conversion processes including optical parametric oscillation, sum/difference frequency generation, and third-harmonic generation.
