A Frequency Quadrupling Optical mm-Wave Generation
... where P2 is the power of second-order harmonics, Pi (i =
0, 1, 3, 4, 5, . . . , i = 2) represents the power of optical carrier
(i = 0) or other undesired harmonics.
Based on Eqs. (9) and (10), the bias offset (δ), the influence
of modulation depth (Md ), the extinction ratio of sub-MZM
(Er ) and no ...
