We demonstrate tunable spectral enhancement of supercontinuum with a long-period grating. The spectral loss of the grating evolves into a peak whose position can be tuned by varying the temperature or the ambient index around the grating.

This paper presents an implement of a broadband clock phase alignment (CPA) for burst mode data recovery deployed in passive optical networks (PON) which are designed to deliver gigabit data rates to the home. A fast and robust CPA has been designed and demonstrated based on the over-sampling & tap-selection technique that the incoming preamble containing a repeated "1010" bit sequence is sampled with multiple clock phases and selects the phase-tap.

A novel optical add-drop multiplexer using arrayed waveguide grating is proposed for optical transport networks. By use of circulators in the coupled fold-back paths between demultiplexed channels, we improve the loss margin and crosstalk performances.
