Abstract

We propose devices for wavelength-division muliplexing based on coupling between different modes in optical fiber. A mode-selective directional coupler (MSDC) couples the LP01 mode of one fiber to the LP02 mode of a second fiber with a bandwidth. -length products of about 4 nmcm an improvement of a factor of 10 over LP01 + LP01 coupling. Refractive index gratings written with UV light can also couple light from the LP01 to the LP02 mode either in a counterpropagating way (Bragg grating) or a codirectional way. Combined with the MSDC they can make efficient channel-drop filters.
