摘要： A multi-port optical device for transferring optical signals, or portion of optical signals, from one transmission element to another is disclosed. The inventive optical device comprises a pair of graded index lenses (103,106) having an interposed Fabry Perot etalon (109). The functionality of the device may be modified by varying the transmission characteristics of the etalon, which may be effected by varying its optical path length. In operation, the optical device utilizes the graded index lenses as image transfer lenses between transmission elements (101,102,107,108) wherein wavelength selectivity therebetween is afforded by the filtering mechanism associated with the etalon. The optical device may be used as a wavelength multiplexer or as an optical splitter. Moreover, by utilizing a piezoelectric transducer, the optical device may be made to operate as an optical switch.
