WebThe Blocking Range tells you the wavelength range blocked by the filter; typically, the range where transmission is less than 50 percent. Bandwidth describes the portion of the spectrum is transmitted through the filter. WebMay 12, 2005 · We demonstrated a non-blocking wavelength channel switch using Thermo-Optic effect of double series coupled polymer microring resonator. This device can switch wavelength channel without blocking other channels. Extinction ratio of more than 10dB was realized.
