Low-Loss Silicon Strip-to-Slot Mode Converters

Low-Loss Silicon Strip-to-Slot Mode Converters

We demonstrate compact highly efficient broadband strip-to-slot mode converters in silicon with record-low losses of 0.02 (±0.02) dB and negligible reflections between 1480 nm and 1580 nm. The new strip-to-slot transition is logarithmically tapered, which enables a compact design. The new logarithmi...

Zusammenfassung:We demonstrate compact highly efficient broadband strip-to-slot mode converters in silicon with record-low losses of 0.02 (±0.02) dB and negligible reflections between 1480 nm and 1580 nm. The new strip-to-slot transition is logarithmically tapered, which enables a compact design. The new logarithmic tapers are compared with more conventional linearly tapered converters.
