“…Operation principle of the mode coupling converters is based on the coupling between the fundamental and the selected high-order mode under the condition of their phase matching. Such a mode coupling is usually achieved by using ADC, [44][45][46][47][48][49][50][51][52][53][54][55][56][57]73,78], ring [58,59], LPG [60][61][62][63][64][65]72,74,75], BG [66,67], dielectric metasurface structure [68][69][70], and grating-assisted coupler [71], and so on. Their key performances have been summarized in Table 2 in the Appendix.…”

“…Their typical fabricated device with optical polymer materials, with a length of 9 mm, shows MCEs from 91% to 99%, MCTs from −23.2 dB to −14.6 dB, and an IL of 10 dB, and these results are weakly sensitive to the polarization state of light and, also, insensitive to temperature. Further in 2016, F. K. Wei et al [51] also experimentally demonstrated a 3D mode converter based on a vertical polymer ADC. Their fabricated device for the conversion of LP01 and LP21a exhibits a maximum MCE of 98.7% at 1550 nm and a 10-dB bandwidth of ~40 nm.…”

Adopting mode division multiplex (MDM) technology as the next frontier for optical fiber communication and on-chip optical interconnection systems is becoming very promising because of those remarkable experimental results based on MDM technology to enhance capacity of optical transmission and, hence, making MDM technology an attractive research field. Consequently, in recent years the large number of new optical devices used to control modes, for example, mode converters, mode filters, mode (de)multiplexers, and modeselective switches, have been developed for MDM applications. This paper presents a review on the recent advances on mode converters, a key component usually used to convert a fundamental mode into a selected high-order mode, and vice versa, at the transmitting and receiving ends in the MDM transmission system. This review focuses on the mode converters based on planar lightwave circuit (PLC) technology and various PLC-based mode converters applied to the above two systems and realized with different materials, structures, and technologies. The basic principles and performances of these mode converters are summarized.
