We present a novel optical sensor based on a one-dimensional photonic crystal slot nanobeam cavity. An ultra-high quality factor of 174,000 is obtained. The sensor possesses an estimated very high sensitivity of 851 nm/RIU.
We propose and experimentally demonstrate a photonic Hilbert transformer using an on-chip silicon photonic crystal nanocavity (PCN). We prove that a PCN can implement photonic Hilbert transformation after certain structure design. The PCN consists of a cavity of three-defect-long (L3) type with a lattice constant of $a = 420$ nm and a hole radius of $r/a = 0.3$. We demonstrate Hilbert transformations...
The phase effects of straight waveguide cavities in the parallel cascaded multiple detuning microring resonators are found significant for multi-channel properties, with peak amplitudes and frequencies of multi-channels studied.
Asymmetric transparent characteristics of parallel cascaded dual detuning microring resonators are investigated in forms of the center cavity detuning, the unbalanced coupling coefficients and the unbalanced loss of dual resonators.
