Expanded mode alignment tolerant optical structures will play an important role in low-cost, large-scale packaging of optoelectronic devices. In this paper, we present two expanded mode structures for operation at 1.55 μm. Our devices use single epitaxial growth and conventional fabrication schemes. High butt-coupling efficiencies (>40%) to a single mode fiber with relaxed alignment tolerances were achieved. The first of our devices uses adiabatic transformation over 500 μm. The second device uses resonant coupling over a much shorter region of 200 μm. The second scheme offers an interesting possibility for monolithic integration of active-passive components. We present the design and simulation results of such an integrated device.
