Abstract

We have devised an ultra-small multi-channel drop filter based on a two-port resonant tunneling system in a two-dimensional photonic crystal with a triangular air-hole lattice. This filter does not require careful consideration of the interference process to achieve a high dropping efficiency. First we develop three-port systems based on a two-port resonant tunneling filter. Next we devise a multi-port channel drop filter by cascading these three-port systems. In this paper, we demonstrate a ten-channel drop filter with an 18 µm device size by 2D-FDTD calculation, and a three-port resonant tunneling filter with 65± 20 % dropping efficiency by experiment.

The thicknesses of the Si-core and the SiO2 cladding are about 200 nm and 3 µm, respectively. The hole diameter is about 210 nm and a=420 nm. P1, P2, P3 and P4 are width-tuned waveguides with widths of W0, 0.90W0, W0, 0.90W0, respectively. The brackets indicate waveguide boundaries. The resonator is a two-point defect cavity with a width of W0. (b) Transmission spectra at P2 and P3. (c) Transmission spectra at P3 and reference (W=W0). The estimated Q factor is about 5000 and the transmittance is 65±20%.

(a) Structure of ten-channel-drop filter composed of twelve width-tuned WGs (WG1 ~WG12) and ten three-point defect resonators (R1~R10). The waveguides and resonators are in sequence by subscript number from the input to the through port. The widths of WG1~WG12 are 1.00, 0.99, 0.98, 0.97, 0.96, 0.95, 0.94, 0.93, 0.92, 0.91, 0.90, 0.89 × W0, respectively. The widths of the R1~R10 are tuned by shifting the four holes on either side of the core to increase or reduce the core width, and their values are 1.09, 1.07, 1.05, 1.03, 1.01, 0.99, 0.97, 0.95, 0.933, 0.915×W0, respectively. The device size (L) is 18 µm when a=400 nm. (b) Calculated transmission spectra of ten-channel-drop filter. All the transmittance values are over 80% and the crosstalk between drop ports is less than -25 dB. This filter can function in the C-band when a=400 nm.
