  • We propose a new structure for creating the Fano resonance and electromagnetically induced transparency couplers. The structure is based on 4x4 multimode interference couplers. The proposed devides have advantages of compactness, large tolerance fabrication. The tranfer matrix method (TMM) and numerical methods are used for analytical analysis and design of the device.

  • We present a study of coupled resonator induced transparency (CRIT) and of coupled resonator induced absorption (CRIA) using only one 4x4 multimode interference coupler and two microring resonators. The structure has advantages of compactness, ease of fabrication on the same chip and no crossover. Our analysis shows that sharp Fano resonance,

  • We propose a method for generating the tunable Fano resonance line sharp by using only one 4x4 multimode interference (MMI) coupler. We show that our new device structure acting an interferometer and we employ a microring resonator and phase shifter to control the shape. The analytical analysis and FDTD simulations have been used for the first order design. The device has advantages of compactness, high tolerance fabrication and ease of fabrication on the same chip.
