“…Examples are coherent optical receivers and transmitters [182], optical beamforming networks [183,184], and circuits may be expanded to operate entire arrays of lasers [185], to provide redundancy or to coherently add their outputs via mutual locking [186]. There is also compatibility with microfluidics [187,188] and thus significant potential for lab-on-the chip and bio sensing applications [189,190].…”

Hybrid integrated semiconductor laser sources offering extremely narrow spectral linewidth as well as compatibility for embedding into integrated photonic circuits are of high importance for a wide range of applications. We present an overview on our recently developed hybrid-integrated diode lasers with feedback from low-loss silicon nitride (Si3N4 in SiO2) circuits, to provide sub-100-Hz-level intrinsic linewidths, up to 120 nm spectral coverage around 1.55 µm wavelength, and an output power above 100 mW. We show dual-wavelength operation, dual-gain operation, laser frequency comb generation, and present work towards realizing a visible-light hybrid integrated diode laser.

“…The ultra‐wide transparency window from visible to mid‐IR renders SiN a versatile option for tremendous emerging applications ranging from 3D PICs, [ 40 ] nonlinear photonics [ 41 ] to biophotonics. [ 41–43 ] The SiN‐on‐silica platform indicates a sufficiently large refractive index contrast and thus tight optical confinement in compact device footprints. Nowadays, multiple commercial foundry platforms including LioniX's TriPleX, [ 44 ] Ligentec's Damascene, [ 45 ] IMEC's BioPIX, [ 46 ] and the IMB‐CNM [ 46 ] aim at developing SiN‐based integrated photonic technologies with ultra‐low propagation loss (<1 dB m −1 ).…”

By virtue of the well‐developed micro‐ and nanofabrication technologies and rapidly progressing surface functionalization strategies, silicon‐based devices have been widely recognized as a highly promising platform for the next‐generation lab‐on‐a‐chip bioanalytical systems with a great potential for point‐of‐care medical diagnostics. Herein, an overview of the latest advances in silicon‐based integrated optofluidic label‐free biosensing technologies relying on the efficient interactions between the evanescent light field at the functionalized surface and specifically bound analytes is presented. State‐of‐the‐art technologies demonstrating label‐free evanescent wave‐based biomarker detection mainly encompass three device configurations, including on‐chip waveguide‐based interferometers, microring resonators, and photonic‐crystal‐based cavities. Moreover, up‐to‐date strategies for elevating the sensitivities and also simplifying the sensing processes are discussed. Emerging laboratory prototypes with advanced integration and packaging schemes incorporating automatic microfluidic components or on‐chip optoelectronic devices lead to one significant step forward in real applications of decentralized diagnostics. Besides, particular attention is paid to currently commercialized label‐free optical bioanalytical models on the market. Finally, the prospects are elaborated with several research routes toward chip‐scale, low‐cost, highly sensitive, multi‐functional, and user‐friendly bioanalytical systems benefiting to global healthcare.

“…The investigated wavelength was 850 nm and the refractive indices of silicon nitride and silicon dioxide were assumed to be 2.02 and 1.46, respectively [37,38]. For this generic silicon nitride photonic platform absorption, scattering, and substrate leakage are neglected because advanced fabrication technologies allow for < 1 dB cm −1 propagation losses in the visible and near-infrared wavelength region [8,[27][28][29]. Therefore, transition and radiative bend mode losses dominate for bends with small radii.…”

“…This formulation allows to implement arbitrary angled bends < 360°. Here, we optimize the partial Euler bend parameter for 45°, 90°and 180°b ends for a low-loss silicon nitride photonic platform [8,[27][28][29] at a wavelength of 850 nm. In difference to previous publications of other groups analyzing various kinds of waveguide bend geometries, our numerical analysis is based on the eigenmode expansion method, which allows a separation of the total losses into bend mode radiation and transition losses along the geometry.…”

In this work we present a detailed analysis of individual loss mechanisms in silicon nitride partial Euler bends at a wavelength of 850 nm. This structure optimizes the transmission through small radii optical waveguide bends. The partial Euler bend geometry balances losses arising from the transition from the straight to the bend waveguide mode, and radiative losses of the bend waveguide mode. Numerical analyses are presented for 45-degree bends commonly employed in S-bend configurations to create lateral offsets, as well as 90-and 180-degree bends. Additionally, 90-degree partial Euler bends were fabricated on a silicon nitride photonic platform to experimentally complement the theoretical findings. The optimized waveguide bends allow for a reduced effective radius without increasing the total bend loss and, thus, enable a higher component density in photonic integrated circuits.
