A novel design of a two-channel optical add-drop multiplexer based on a self-rolled-up microtube （SRM） is presented. This design consists of an SRM that has a parabolic lobe-like pattern along the tube＇s axial direction, as well as straight silicon waveguides and a 180° waveguide bend. The vertical configuration of the SRM and waveguides is analyzed by the coupled mode theory for achieving the optinmm gap. In the critical coupling regime, when the device serves as an optical demultiplexer, the minimum insertion loss is 1.94 dB, and the maximunl channel crosstalk is -6.036 dB. Also, as an optical multiplexer, the maximum crosstalk becomes -11.9 dB.

In order to study the dark current characteristics in a quantum wire infrared photodetector(QRIP),the average number of electrons in quantum wires(QRs) must be got,which is mostly too *** this paper we give a simple formula to calculate the average number of carriers in a quantum wire(QR) that can be easily evaluated by mathematical softwares,and then we use this formula to study dark current characteristics of a quantum wire infrared photodetector(QRIP).
