Title: Intermode loss difference compensation device
Inventor: SAKAMOTO YASUSHI
IPC: G02F1/01
Filed: 2019-03-14
Abstract: To provide an intermode loss difference compensation device capable of setting loss for LP01 mode with causing little loss to LP11 mode.SOLUTION: The intermode loss difference compensation device includes: two waveguides of a waveguide 101 and a waveguide 102; coupling parts 103 and 104 coupling the two waveguides 101 and 102 in close proximity; and a delay part 201 positioned between the two coupling parts 103 and 104 for causing a delay difference in the waveguide 101 and the waveguide 102. The parallel waveguide length Lc of the coupling parts 103 and 104 is controlled to change the coupling efficiency between the modes of the coupling parts 103 and 104. By changing the waveguide length (Ld and Lm) of the delay part 201 and the refractive index of the waveguide 101 or 102, a phase difference Δθ is generated between waveguides in the delay part 201 to thereby give an intermode loss difference between LP01 mode and LP11 mode.SELECTED DRAWING: Figure 6
