Achieving Low Propagation Loss and Small‐Index‐Contrast Carbonized Porous Silicon Waveguides Using Direct Laser Writing

Achieving Low Propagation Loss and Small‐Index‐Contrast Carbonized Porous Silicon Waveguides Using Direct Laser Writing

Porous silicon (PS) is often overlooked as a platform for creating large‐mode area waveguides suitable for optical sensing applications due to challenges around creating laterally confined (in‐plane) open‐pore waveguide structures in the PS film. Direct laser writing (DLW) in hydrocarbon atmospheres...
