communication; Introduction
Today, infrared (IR) photonic integrated circuits (PICs) represent a well-established technology with numerous applications in optical telecommunications [1][2][3][4]. However, for life science applications (biosensors, molecular diagnostics, food inspection, etc.) visiblelight
design reported in the literature with a coupling efficiency of only 8.7%, we propose an optimized photonic platform with efficiency reaching 65.5%.

communication systems are required [5][6]. The technology for visible wavelength PICs is much less mature than for IR PICs, and different approaches have been explored. One exploratory approach for visible photonics consists of the monolithic integration of InGaN emitters/detectors with GaN-based waveguides [7
