An integrated, high-order phase-shifted Bragg-grating realizing steep-sloped optical passband filter with measured 41.5 dB out-of-band rejection and a transition bandwidth roll-off of 288 GHz/nm is demonstrated in passive Silicon-on-Insulator technology and verified in two different microwave photonics applications.
