Performance of 1550 nm VCSEL at 10 Gb/s in G.655 and G.652 SSMF

1550 nm high contrast grating VCSEL.

We demonstrate an electrically pumped high contrast grating (HCG) VCSEL operating at 1550 nm incorporating a proton implant-defined aperture. Output powers of >1 mW are obtained at room temperature under continuous wave operation. Devices operate continuous wave at temperatures exceeding 60 degrees C. The novel device design, which is grown in a single epitaxy step, may enable lower cost long w...

Performance Evaluation of EPON Link at 1550 and 1350 nm using NRZ and RZ Modulation Technique

The research work has evaluated the performance of the proposed link in terms of QFactor and BER at wavelength of 1550 nm and 1350 nm at transmission distance of 30 km. The comparison has also been drawn among the proposed EPON link with NRZ and RZ modulation scheme. In this work, simulative investigation to evaluate the performance of EPON transmission links using NRZ and RZ modulation schemes...

Optical Absorption of Silicon Nitride Membranes at 1064 nm and at 1550 nm

Performance Assessment of 1310 to 1550 nm Wavelength Conversion

We report on all-optical 1310 to 1550 nm wavelength conversion and NRZ-to-RZ data format conversion based on nonlinear polarization rotation in a single semiconductor optical amplifier. Introduction Undoubtedly, the 1310 nm transmission window is experiencing renewed interest. Multi-Gbit/s 1310 nm transmission technology is employed in access and metro networks [1-2]. The long-haul core network...

Nonlinearities in porous silicon optical waveguides at 1550 nm.

We report an experimental investigation of the nonlinear optical properties of nanoporous silicon optical waveguides measured at 1550 nm. The nonlinear properties including two-photon absorption, self-phase modulation, free-carrier absorption and free-carrier plasma dispersion are characterized and compared with similar measurements conducted on a conventional silicon-on-insulator ridge wavegui...
