A periodic optical filter for interleaving a plurality of optical signals to provide a multiplexed signal for transmission over an optical fiber is disclosed. The periodic optical filter includes a first optical filter constructed to receive at least two optical signals through an input port to provide at least one filtered optical signal. The periodic optical filter also includes a second optical filter, in communication with the first optical filter, constructed to receive the filtered optical signal from the first optical filter through an intermediate port to provide a multiplexed signal for transmission through an output port. At least one of the optical filters includes an infinite-impulse response filter and at least one of the optical filters includes a finite-impulse response filter. Methods of fabrication and methods of use including the periodic optical filter are disclosed.

A wavelength division multiplexing system has a wavelength division multiplexer and a wavelength division demultiplexer. The wavelength division demultiplexer is in series with the wavelength division multiplexer to process at least one optical signal to generate at least one processed optical signal. The wavelength division multiplexer and the wavelength division demultiplexer cooperate to introduce substantially zero total chromatic dispersion in the processed optical signal. In one version, the wavelength division multiplexer and the wavelength division demultiplexer introduce opposing functions of chromatic dispersion into the at least one processed optical signal.

An optical device includes a first waveguide having an end portion configured to receive an optical signal, the optical signal having a fundamental mode; a second waveguide having an end portion spaced from the end portion of the first waveguide; and a cladding layer surrounding the first and second waveguides. The first waveguide is configured such that the optical signal undergoes multimode interference to focus the fundamental mode at the end portion of the second waveguide.
