Abstract
An optical package comprises an optical element (e.g., a filter), a reflective surface, an input optical fiber and an output optical fiber. A light signal travels through the input fiber and through the element where it is shaped or modified a first time. The shaped light signal is reflected by the reflective surface and is again transmitted through the element where it is shaped or modified a second time. The twice-shaped light signal then travels out through the output fiber. The package thereby utilizes the element two times. The package is useful in wavelength division multiplex (WDM) telecommunication systems and other light processing systems.
