Abstract

Research on integrated blue and near-ultraviolet photonics has been increasingly investigated in recent years. To enable the development of photonic integrated circuits in this wavelength range, one of the challenges is to identify a transparent platform that can provide a variety of integrated components. Aluminum oxide (Al₂O₃) was demonstrated to exhibit low propagation losses for wavelengths below 450 nm, making it a very promising platform to operate at short wavelengths. MMIs are very convenient integrated components for splitting or combining signals and can be used for many applications such as on-chip spectrometry or microscopy. The development of a 50/50 coupler at 405 nm is reported based on symmetrical multimode interferometer (MMI) presenting a splitting ratio of

$3.20~\pm ~0.34$

dB/MMI. Characterizations at 375, 420, and 454 nm are also presented.

基于多模干涉仪的氧化铝50/50分光器用于蓝/近紫外光谱范围

近年来，蓝光和近紫外集成光子学的研究日益受到重视。为了使光子集成电路在这个波长范围内的发展，挑战之一是确定一个透明的平台，可以提供各种集成组件。氧化铝（Al2O3）在450nm以下的波长下表现出较低的传播损耗，使其成为一个非常有前途的短波长平台。mmi是非常方便的集成组件，用于分裂或组合信号，可用于许多应用，如片上光谱或显微镜。本文报道了一种基于对称多模干涉仪（MMI）的50/50耦合器的研制，其分光比为3.20~ 0.34美元dB/MMI。还介绍了375、420和454nm的表征。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
