All-optical 40Gb/s cross-wavelength transferred clock recovery for 3R wavelength conversion using a traveling wave electroabsorption modulator-based resonant cavity

An all-optical, compact clock recovery is demonstrated by utilizing filtered and actively amplified photocurrent in a traveling-wave electroabsorption modulator. 40 GHz optical clock was recovered from 40 Gb/s OTDM and transferred to new clock wavelength.
