説明
SUMMARYA waveguide type optical frequency comb (WG-OFC) generator was developed at 1 . 5 ii mwavelength region by utilizing a waveguide type phase modulator. It was confirmed that theenvelope of sidebands spectrum had a width of 4.3THz. For further expansion of this span of theOFC, a multiplex optical frequency comb generation system was assembled, , and modulationsidebands were generated for a span as wide as 1 OTHz. By the heterodyne detection between two OFCs whose central frequencies are separated as large as O.4THz, a frequency offset locking between the two OFCs was realized.6.REFERENCES[1] R.E.Drullinger, K.M.Evenson, D.A.Jennings, F.R.Petersen, J.C.Bergquist, and L.Burkins, "2.5- THz frequency difference measurement in the visible using metal insulator-metal diodes," Appl.
