Currently, extensive efforts are being made world wide to develop photonic devices capable of multifunctionality for advanced network systems. These systems at 1.3 μm and 1.5 μm require a combination of transmitters, optical amplifiers, splitters, and switches with high speed, bandwidth, and gain. One device of particular interest is a splitter that is used to broadcast or to simultaneously route a signal to a number of ports or subscribers (1 x N and N x N splitting). Various deigns have been proposed such as cascaded Y-Branch and multimode interference devices. Passive splitters require pre-and/or post-amplification to compensate for splitting loss. For 1 x N splitters with large N, power saturation effects in single-mode amplifiers limit pre-amplification so post-amplification is also usually required. Post-amplification; however, adds noise to the outputs and fails to alleviate the signal-to-noise ratios approaching that of the pre-amplification case without power saturation effects.

520 $a Currently, extensive efforts are being made world wide to develop photonic devices capable of multifunctionality for advanced network systems. These systems at 1.3 μm and 1.5 μm require a combination of transmitters, optical amplifiers, splitters, and switches with high speed, bandwidth, and gain. One device of particular interest is a splitter that is used to broadcast or to simultaneously route a signal to a number of ports or subscribers (1 x N and N x N splitting). Various deigns have been proposed such as cascaded Y-Branch and multimode interference devices. Passive splitters require pre-and/or post-amplification to compensate for splitting loss. For 1 x N splitters with large N, power saturation effects in single-mode amplifiers limit pre-amplification so post-amplification is also usually required. Post-amplification; however, adds noise to the outputs and fails to alleviate the signal-to-noise ratios approaching that of the pre-amplification case without power saturation effects.
520 $a In this work, a first generation of 1 x N tapered amplifier power splitter (TAPS) was developed to study the feasibility of amplifying signals during the spitting process. The TAPS device equally splits the signal from an input guide into N output guides using a 2D-slab waveguide diffraction region. This region also serves as a tapered amplifier. The first working prototypes of this novel device technology, 1 x 8 and 1 x 16 all-active 1.3 μm wavelength TAPS devices, with gains as high as 14 dB per output channel, are reported.
520 $a The dissertation details the design, fabrication, packaging, and testing the 1 x 8 and 1 x 16 TAPS devices and shows that with straight-forward evolutionary modifications to the initial design, 1 x 32 and 1 x 64 devices with significant gain per output channel are feasible.
