Xl. Fu et Jm. Xu, A NOVEL GRATING-IN-ETALON WDM DEVICE AND A PROOF-OF-CONCEPT DEMONSTRATION OF A 1X40 POLARIZATION-INSENSITIVE WDM, IEEE photonics technology letters, 9(6), 1997, pp. 779-781
We propose a novel grating-in-etalon device for wavelength division mu
ltiplexing (WDM) applications. After presenting the device concept and
a specific design of the device configuration, we report a first proo
f-of-concept demonstration of a 1 x 40 polarization insensitive WDM de
vice in LiNbO3.
