And Performance

The technology and system applications of high speed OEIC transmitters are discussed in this paper. With only two MOCVD growths and conventional processing techniques, OEIC transmitters made of sophisticated DFB laser diodes and InGaAs/InAlAs MODFETs can be fabricated. A speed of 10 Gbit/s has been demonstrated. Using the same technology, OEIC transmitters for high bit rate time division multiplexed (TDM) and dense wavelength division multiplexed (WDM) systems are designed and fabricated. There is evidence showing that the OEIC transmitter integrated with multiplexers and other critical circuits can offer significant cost reduction and performance improvement compared to hybrid approach. Using a four-channel OEIC WDM transmitter, we demonstrate its capability of precise wavelength control by setting the channel spacing as close as 0.3 nm. Finally, the crosstalk of OEIC is analyzed. Bonding wires are confirmed as the dominant factor for RF crosstalk. To keep the thermal crosstalk within an acceptable level, a proper device spacing to substrate thickness ratio has to be chosen.

Wavelength division multiplexed passive optical network has emerged as a promising solution to support a robust and large-scale next generation optical access network. It offers high-capacity data delivery and flexible bandwidth provisioning to all subscribers, so as to meet the ever-increasing bandwidth requirements as well as the quality of service requirements of the next generation broadband access networks. The maturity and reduced cost of the WDM components available in the market are also among the major driving forces to enhance the feasibility and practicality of commercial deployment. In this chapter, the author will provide a comprehensive discussion on the basic principles and network architectures for WDM-PONs, as well as their various enabling technologies. Different feasible approaches to support the two-way transmission will be discussed. It is believed that WDM-PON is an attractive solution to realize fiber-to-the-home (FTTH) applications.

AbstractHigher spectral efficiency and data rate per channel are the most cost-effective approaches to meet the exponential demand of data traffic in optical fiber network communication system. In this paper, diverse modulation formats are analyzed for Dense Wavelength Division Multiplexed system at 100 Gbps * 16=1600 Gbps data rates. The performance analysis of proffered system for Non-Return to Zero, Return to Zero, Carrier- Suppressed Return to Zero and Duo binary RZ with duty cycle 0.5 to 0.7 ranges like modulation formats are considered to find optimum modulation format for a 100 Gbps bit rate per channel optical fiber transmission network system. The simulations are analyzed for different values of input power, length of fiber, nonlinear refractive index, nonlinear dispersion and nonlinear effective area for all above mentioned modulation formats with spacing 100 to 250 GHz. to evaluate the effect of modulation format Fiber Bragg Gratting, optical fiber amplifier and Dispersion Compensation Fiber dispersion compensation techniques are enacted on this proposed optical network system.

We develop and study the physics of a novel hybrid wavelength-division-multiplexed, optical timedivision-multiplexed (WDM-OTDM) mode-locked semiconductor laser for applications in ultra-high data rate communication links, computer interconnects, and optical sampling applications. The key philosophy behind using a hybrid approach is that state-of-the-art system performance can be achieved without the necessity of operating at the limits of a either a pure WDM or OTDM technology platform.
