We present a series of epitaxial studies resulting in reduced waveguide loss and improved quantum efficiency for waveguides and amplifiers respectively on InP. Combined with improved router designs and optimized active/passive transitions, these advances make the fabrication of many large scale (>1 cm) devices practical. We will demonstrate low threshold waveguide grating router (WGR) based lasers, a 9×9 optical spatial cross connect, and a dynamic power equalizer
