AGILE OPTICAL COMPONENTS Dual Parallel Mach-Zehnder (DPMZ) Modulator Key Features Monolithically integrated, parallel, high-speed MZ modulators, with a phase modulator superstructure High-speed MZ modulators with matching amplitude and phase response High electro-optic bandwidth Compatible with full band tunable lasers Integrated RF power monitors for precision control Single-sided electrical I/O Applications 40 Gbps metro, regional and LH optical networks 10 Gbps ULH optical networks Spectrally efficient DQPSK modulation The dual parallel Mach-Zehnder (DPMZ) modulator is ideally suited for use in metro, long-haul (LH) and ultra long-haul (ULH) optical transport applications. It is used for spectrally efficient multisymbol transmission based on differential quadrature phase shift keying (DQPSK) modulation. The DPMZ modulator is comprised of two matched, high-speed Mach-Zehnder (MZ) modulators that are monolithically integrated, in parallel, inside an MZ superstructure. The MZ superstructure also functions as a phase (shifter) modulator. DPMZ modulators are specifically designed to yield well-behaved and matching electro-optic amplitude and phase responses over a 20 GHz frequency range and to have enhanced extinction ratios. The DPMZ is available with either singlemode or polarization maintaining output fiber. For mounting convenience and space efficiency, the modulator is designed with the electrical I/O located on one side of the package. The two RF inputs use ……
