“…In previous works, we have reported adequate edge coupling to the developed PIC technology, both from fibers as well as from free space collimated beams inside an assembled optical module 25 . We have also introduced a low-loss multiplexer device concept adjustable to target wavelengths in the entire visible range and capable of combining the targeted 405 nm, 488 nm, 561 nm, and 640 nm wavelengths 25 . Here, we report on the complete characterization of one of the developed MLE system chips combining multiplexing with wavelength selective variable optical attenuation.…”

We are reporting on a Multi-Color Laser Engine (MLE) multiplexing four wavelengths (405 nm, 488 nm, 561 nm, 640 nm) by means of a Photonic Integrated Circuit (PIC) with Silicon Nitride (SiN) waveguides. Multiple building blocks are tested that allow manipulating the light in the waveguides to achieve fiber switching and variable optical attenuation. To slow down facet degradation and extend chip lifetime at near Ultra-Violet (UV) wavelengths (405 nm), a lateral endcap is implemented on chip and tested for reliability. Reasonable coupling and on-chip losses have been achieved in view of a practical use of the technology.

Semiconductor light sources technology has seen tremendous strides in recent decades and a rapidly increasing interest in it. The unique advantages and characteristics of this form of light generation include compactness, high efficiency, and reliability. With these recent advancements, light-emitting diodes (LEDs), laser diodes, and superluminescent diodes (SLDs) have become an indispensable part of our homes, factories, and research facilities. In particular, the sensitivity of the human eye to the visible range of the electromagnetic spectrum ranging from 400 to 700 nm and the wavelength-dependence of optical characteristics of materials make visible light required for a plethora of applications ranging from displays for entertainment, to imaging in the medical field, to light-based atomic clocks. While LEDs are the most commonly found type of semiconductor light sources, laser diodes and SLDs are of special interest due to their higher output optical power, spectral purity, and coherence. In this tutorial, we first go over the main unique characteristics of the different types and configurations of visible-light laser diodes and SLDs and their general structures with a focus on their advantages compared to LEDs. We then discuss the applications in which these characteristics are of great interest in the fields of displays, communication, instrumentation, and photonic integrated circuits.

“…Laser diodes can be in the same price range, but get more expensive if additional features, such as tunability, are desired. VIS PICs already found applications in optofluidics and biosensing, where refractive index sensing methods can be employed [55,[58][59][60].…”

In this article, the potential of photonic integrated circuits (PICs) for modern gas sensing applications is discussed. Optical detection systems can be found at the high-end of the currently available gas detectors, and PIC-based optical spectroscopic devices promise a significant reduction in size and cost. The performance of such devices is reviewed here. This discussion is not limited to one semiconductor platform, but includes several available platforms operating from the visible wavelength range up to the long wavelength infrared. The different platforms are evaluated regarding their capabilities in creating a fully integrated spectroscopic setup, including light source, interaction cell and detection unit. Advanced spectroscopy methods are assessed regarding their PIC compatibility. Based on the comparison of PICs with state-of-the-art bulk optical devices, it can be concluded that they can fill the application space of compact and low cost optical gas sensors.
