“…This calculation ensures that all the light from the input star coupler is collected by the input array aperture [49]. For these calculations, we utilized the AWG-Parameters tool [18,50], which grounded in the model of Smit and van Dam, and it has already been employed in numerous AWG designs, with successful experimental validation [19,21,[49][50][51]. The AWG design parameters for the 512-channel AWG-spectrometer were computed based on a central wavelength of λc = 850 nm and a resolution of 0.1 nm (also referred to as channel spacing), corresponding to a frequency of df = 42 GHz.…”

“…In previous studies aimed at miniaturising OCT, tomograms were acquired using spectral domain (SD)-OCT systems that replaced single optical components, such as interferometers [11], delay lines [12], or diffraction gratings [13][14][15], with PICs. A PIC-based analogue to a diffraction grating is an arrayed waveguide grating (AWG) [16][17][18][19][20]. It can be used in SD-OCT to separate broadband light into its different wavelengths.…”

Photonics integrated circuits (PICs) represent a promising technology for the much-needed medical devices of today. Their primary advantage lies in their ability to integrate multiple functions onto a single chip, thereby reducing the complexity, size, maintenance requirements, and costs. When applied to optical coherence tomography (OCT), the leading tool for state-of-the-art ophthalmic diagnosis, PICs have the potential to increase accessibility, especially in scenarios, where size, weight, or costs are limiting factors. In this paper, we introduce an unprecedented fully integrated CMOS-compatible spectrometer, an optoelectronic system based on PIC for spectral domain OCT. To achieve this, we co-integrated a 512-channel arrayed waveguide grating with electronics. We successfully addressed the challenge of establishing a connection with minimal losses between the optical components and photodiodes co-integrated on a chip achieving a transmission efficiency of 70%. With this fully integrated PIC-based spectrometer interfaced to a spectral domain OCT system, we achieved a sensitivity of 92dB at an imaging speed of 55kHz, with a 6dB signal roll-off occurring at 2mm. We applied this innovative technology successfully to obtain 3D in vivo tomograms of zebrafish larvae and human skin. This ground-breaking fully integrated spectrometer represents a significant step towards a miniaturised, cost-effective, and maintenance-free OCT system.

Silicon-on-insulator (SOI) has become one of the popular material that is widely used to develop passive or active devices in application for modern photonics communication. Using SOI, we proposed a new double S-shaped Arrayed Waveguide Grating (AWG) with broad channel spacing of 20 nm (~2500 GHz). This SOI-based AWG device performed with low insertion loss of <3.74 dB for a total of 16 channels where it covers the wavelength from 1311 nm to 1611 nm. The successful design of SOI-based AWG was then applied in CWDM system configuration where 10 Gb/s and 40 Gb/s data rates were used with optimized thermal noise inside the InGaAs pin photodiode and InGaAs Avalanche Photodiode (APD) at the system receiver. The maximum length of fiber was investigated for both photodetectors before the signal degraded when the bit error rate (BER) became worse than 10 -9 . Apparently, the distance of fiber can reach over 50 km when InGaAs APD was used for this system. Overall, this device that was developed on SOI material possibly increased the transmission capacity for application in metro access network.
