چکیده انگلیسی
A novel design of a single ring resonator with two low-loss 2Ã2 90-degree multimode waveguide turning mirror couplers based on a InP structure. The coupling factor of the 2Ã2 90-degree multimode waveguide turning mirror coupler is inversed for K=0.85 to K=0.15 when one folding is achieved. The 2Ã2 90-degree turning mirror coupler for K=0.15 is (3/4)LÏ in length. Its length is reduced 3 times than the conventional straight 2Ã2 multimode waveguide interference coupler (9/4)LÏ in length for K=0.15. The cavity length of the curve waveguide (90-degree arc length) in this ring resonator with two 2Ã2 90-degree multimode waveguide turning couplers is decreased 1/2 times than with two 2Ã2 MMI couplers (180-degree arc length). The free spectral range (FSR) is increased 2 times. The output spectral response gets a FSR of 82Â GHz for the device and a contrast of 4Â dB and FWHM of 0.24Â nm for the drop port. The results of numerical analysis calculated by the transfer functions in a single ring resonator are agreement with the experimental results.
