چکیده

For precise chirp parameter control, we investigated xcut LiNbO3 single-drive asymmetric Mach-Zehnder modulators with extinction-ratio adjustable active Y-branch structures, which can enhance on-off extinction ratio. The chirp parameter of the modulated output was precisely measured by using high extinction ratio operation. Experimental results show that it is possible to fabricate modulators with desired chirp parameters.

Overcoming Chromatic-Dispersion Effects in Fiber-Wireless Systems Incorporating External Modulators

We demonstrate two techniques to reduce the effects of fiber chromatic dispersion in fiber-wireless systems incorporating external modulators. We theoretically and experimentally show that the achievable link distance can be increased by varying the chirp parameter of the modulator to give large negative chirp using a dual-electrode Mach–Zehnder modulator (MZM) biased at quadrature. In addition...

100-Gbit/s Amplitude and Phase Modulation Characterization of a Single-Drive, Low-Vπ Polymer Mach-Zehnder Modulator

A polymer single-drive Mach-Zehnder modulator is experimentally characterized using 100-Gbit/s serial data modulation. BER of 10 is achieved for both 100-Gbit/s NRZ-OOK and NRZ-DPSK signals without optical or electrical equalization. The modulator shows a 7-dB bandwidth at 110-GHz and the chirp as low as -0.0219 GHz. © 2012 Optical Society of America OCIS codes: (060.4510) Optical Communication...

Replica-molded electro-optic polymer Mach–Zehnder modulator

A Mach–Zehnder electro-optic polymer amplitude modulator is fabricated by a simple and high-throughput soft-stamp replica-molding technique. The modulator structure incorporates the highly nonlinear and stable chromophore, AJL8, doped in amorphous polycarbonate. Single-arm phase-retardation results in a halfwave voltage sVpd of 8.4 V at 1600 nm. The on/off extinction ratio is better than 19 dB,...

Large Signal Analysis of Mach-Zehnder Modulator Intensity Response in a Linear Dispersive Fiber

Two novel theoretical models that give the intensity of the optical signal generated by a Mach-Zehnder modulator through a dispersive medium are reported. These models include the chirp and dispersion factors and can be used for largesignals and for large values of the chirp parameters. Theoretical results are in good agreement with the simulation.
