“…32 On the other hand, directional couplers need tight ͑ϳ0.1 m͒ control of the waveguide dimensions since they exploit mode coupling between two waveguides that are close to each other. 33 When compared with directional couplers, MMI couplers show better uniformity, polarization insensitivity, 5 and bandwidth and fabrication tolerances 3 and are more suitable for an MZI-type optical switch. Second, with a Y-junction, MMI couplers show better polarization insensitivity and fabrication tolerances.…”

Abstract. Photonic switches are becoming key components in advanced optical networks due to their various applications in optical communication. One of the key advantages of photonic switches is the fact that they redirect or convert light without any optical to electronic conversions and vice versa. As one type of optical switch, multimode interference ͑MMI͒ switches have received more attention in recent years due to their significant role. The structure and operation principle of various types of MMI switches are introduced, and the recent progresses of MMI switches are also discussed.

“…4,5 At the same time, this can be applicable in splitters and combiners, 6 mode converters, 7 and power splitters with arbitrary splitting ratio. 8 Only recently, their use has been expanded from passive to active devices, and several photonic switches have been proposed using MMI effects.…”

“…Self-imaging is a property of multi-mode waveguides by which an input field profile is reproduced in single or multiple images at periodic intervals along the propagation direction [12,19]. The 2D PhC is formed by a triangular configuration with lattice pitch of Λ=380 nm and air hole diameter of D=222nm.…”

Based on inspiration from multi-mode interference self-imaging and theoretical FDTD simulations, a 1x3 beam splitter was designed, fabricated and characterized. Measurements show that for TE-polarized incident light the power is distributed equally between the output ports within 1dB in the range from 1541nm to 1552nm, and the total transmission of the 1x3 splitter is equal to the corresponding length of a single-linedefect PhCW within the measurement uncertainty.

“…Optical switches based on multimode interference (MMI) couplers, have gained considerable popularity in recent years. MMI couplers have compactness [5][6][7], relaxed fabrication tolerance, and low wavelength dependent loss (WDL) [8], as well as low polarization dependent loss (PDL) [9,10] and suitability for device integration [11] which are the subject of interest in high capacity WDM network. All these features make MMI an ideal choice compared to directional couplers or Y-branches.…”

Abstract-The 2 × 2 MMI polymer thermo-optic switch in a high refractive index contrast (0.102) with a new structure design is realized. This device was fabricated using standard fabrication techniques such as coating, photolithography, and dry etching. A crosstalk level of −36.2 dB has been achieved. Meanwhile the extinction ratio of 36.1 dB has been achieved in this device. The polarization dependent loss (PDL) of 0.3 dB and Insertion loss of 1.4 dB were measured at 1550 nm wavelength. In terms of wavelength dependency, the device shows a good performance within C-band wavelength with vacillation of the insertion loss value around 0.88 dB. The power consumption of 1.85 mW was measured to change the state of the switch from the cross to bar state. The measured switching time was 0.7 ms.
