摘要
A hitless wavelength selective optical device includes a first thermo-optic switch (TOS), a second TOS, a first waveguide, a second waveguide, a third waveguide, a heating element and a control unit. The first TOS includes receives a wavelength division multiplexed (WDM) signal at a first port of the first TOS. The second TOS provides at least one channel of the WDM signal at a first port of the second TOS. The first waveguide is coupled between second ports of the first and second TOS. The second waveguide includes a tunable filter that reflects a selected channel from the received WDM signal and coupled between the third ports of the first and second TOS.
