High efficiency silicon nitride grating coupler
In this paper, we have designed, fabricated and characterized silicon nitride grating couplers with high efficiency at 1490 nm. The devices are fabricated using deep UV photolithography with resolution requirement of ∼500 nm. The grating coupler fabricated yields a peak coupling efficiency of −5.1 d...

Zusammenfassung: | In this paper, we have designed, fabricated and characterized silicon nitride grating couplers with high efficiency at 1490 nm. The devices are fabricated using deep UV photolithography with resolution requirement of ∼500 nm. The grating coupler fabricated yields a peak coupling efficiency of −5.1 dB. The 1-dB bandwidth of the grating coupler is 60 nm. |
