COMPACT WAVELENGTH FILTER INTEGRATED TO A SINGLE-MODE OPTICAL FIBER |
摘要 |
A wavelength filter is integrated to a single-mode optical fiber capable of propagating a light signal and comprising a longitudinal and opaque outer jacket enveloping the fiber. This fiber is stripped of its jacket on a given length thereof to obtain a non-jacketed length of optical fiber. The so produced non-jacketed fiber length is formed with first and second concatenated biconical tapers separated from each other by a given distance and each having a given profile. By appropriately selecting the distance separating the two tapers and the given profile thereof, the filter will enable transmission of a first, predetermined wavelength of the propagated light signal while it will stop a second, predetermined wavelength of the signal. A method of integrating such a filter to a single-mode optical fiber is also proposed. |
