 | This report describes the results of dispersion and nonlinearity experiments of the components required for the development of picosecond passively mode-locked fiber lasers. First, we will summarize the interferometric dispersion measurement technique and results for short lengths of fiber (< 1 meter). We measured dispersion of standard fiber at 16.9 +/- 1.4 ps/nm and Er- doped fiber at 8.5 +/- 1.6 ps/nm at 1550 nm. Next, we measured the group ... |

| An experimental study of the mode-locking process in erbium-doped fiber lasers (EDFL's) operating at 1.55 microns using multiple quantum well saturable absorbers is presented. The self-starting passively mode-locked laser was constructed in a Fabry-Perot configuration using the saturable absorber as the back reflector of the cavity. Picosecond pulses that range from 14.2 to 38.8 ps were generated using a series of saturable absorbers. The pulse widths were dependent upon the ... |

| This report describes the results of experiments performed in various areas of material and component technology required for the development of multiple gigabit per second fiber based optical interconnect and optical communication links. First, we will summarize the development of a chromium- doped:YAG (Cr(4+): YAG) solid state laser for use in the 1500 nm transmission window of optical fiber. The Cr(4+): YAG laser produces tunable femtosecond pulses from 1488 to ... |

| This report describes the results of experiments performed in various areas of material and component technology required for the development of gigabit optical interconnect and communication systems. First, we will summarize the analysis of transient and optoelectronic feedback sustained pulsation of laser diodes at 1300 nm for use as frequency variable sources in time division optical systems. Next, we describe the design and characterization of a colliding pulse Mach Zehnder ... |

| This report describes the results of experiments performed in various areas of technology required to develop gigabit optical interconnects for communication at 1.3 micrometer wavelength. First, we will summarize the analysis of optical correlation switches (i.e. optical AND gates) for use in time-division optical interconnects. Next, we describe the design and characterization of an all-optical, 30db contrast ratio GaAlInAs multiple quantum well asymmetric reflection modulator. Then, we comment on the ... |

|
| A novel design for electro-optic modulators operating at wavelengths compatible with fiber-based optical interconnects and networks is presented. This design uses InGaAs/InAlAs asymmetric coupled quantum wells (ACQWS) to enhance the electro-optic effect within the material and results in a low power modulator capable of high-speed operation. A device was fabricated which shows real charge transfer between the ACQWs. This device shows that without modulation doping and real charge transfer the ... |

| Electro-optics modulators are a necessary component of emerging optical fiber based local area interconnects. One type of modulator, suitable for use in optical interconnects, is an asymmetric Fabry-Perot reflection modulator (ARM). This type of an intensity modulator uses an electro-optic material as the spacer material to balance the normally unequal front and back mirror reflectances. The quantum confined Franz-Keldysh and Stark effects shift the absorption edge of semiconductor multiple quantum ... |
