All-fiber zero-insertion-loss add-drop filter for wavelength-division multiplexing.
نویسندگان
چکیده
We developed and fabricated an all-fiber add-drop filter by recording a Bragg grating in the waist of an asymmetric mode converter-coupler formed by adiabatic tapering and fusing of two locally dissimilar, single-mode optical fibers. The insertion loss of the device was ~0.1 dB .A narrow spectral bandwidth (<1 nm) and a large add-drop efficiency (>90%) were also demonstrated. In addition, the filter was polarization independent.

متن کاملCoupled-mode analysis of fiber-optic add drop filters for dense wavelength-division multiplexing.
We present a coupled-mode theory of fiber-optic add-drop filters, which involve directional coupling between two fibers combined with fiber Bragg gratings defined inside the coupling region. The analysis self-consistently accounts for both the directional and the reflection coupling, and the propagation constants and structure of the supermodes of the combined structure are derived. We present ...

There have been increasing interests in programmable optical add-drop multiplexers (OADM) and wavelength-selective switches in wavelength-division-multiplexed (WDM) networks. Conventional OADM has one input and one output channels, in addition to an add and a drop channels [l]. It is also called 1x1 OADM. Dynamic OADM with more than one output ports offers greater flexibility and functionality ...
