However, most conventional IOMs are restricted to specific spectral bands. Here, we leveraged the wide transparency window of lithium niobate in conjunction with the two -pulley coupled resonator method. This approach led to the development of a hyperband electro-optic (EO) modulator that operates over an expansive spectral range from 775 to 1550 nm on a single device. The demonstrated EO modulator exhibits half -wave voltage -length products of 0.25, 0.93, and 0.68 V center dot cm at wavelengths of 1539.50, 969.70, and 775.17 nm, respectively.
