Optical add-drop multiplexer (OADM) is a device to add and drop the branch signals in the optical domain , as the core equipment of all optical network.Researchers at the University of Shiraz, Iran, designed a new a two-channel OADM consisting of an self-rolled- up microtube (SRM) that has a parabolic lobe-like pat-tern along the tube’s axial direction, as well as straight silicon waveguides and a 180° waveguide bend. The SRM includes one free-standing part and two legs. The straight waveguides, which are placed close to the SRM along the axial direction, are introduced as the in-put-through and add-drop ports, and the free-standing part of SRM acts as a resonator. The vertical configura-tion of the SRM and waveguides was analyzed for an optimum gap. The OADM has the best performance with the channel spacing of 1.6 nm and the minimum insertion loss value of 1.94 dB.The new OADM is small in size, low in insertion loss, and suitable for integrated circuits, which can be used for chip-level interconnect technologies for optical networks.
