Whereas considerable interest exists in self-assembly of well-ordered, porous "inverse opal" structures for optical, electronic, and (bio)chemical applications, uncontrolled defect formation has limited the scale-up and practicality of such approaches. Here we demonstrate a new method for assembling highly ordered, crack-free inverse opal films over a(More)
Owing to its attractive optical and electrical properties, large surface to volume ratio, and ease of surface modifi cation, porous silicon (pSi) has been extensively studied in a variety of applications, such as light emitting diodes, [ 1 ] photodetectors, [ 2 ] optical switches, [ 3 ] lithium ion batteries, [ 4 ] and label-free optical detection of(More)
We develop a model for silicon-on-insulator microresonators with magnesiothermically-formed porous silicon cladding possessing three-dimensional interconnected pores. Investigation of waveguide design and geometrical parameters indicates an optimized areal mass sensitivity of ~ 0.2 pm/(pg/mm<sup>2</sup>).

Colloidal self-assembly holds promise for photonic applications as a solution-based, low-cost alternative to top-down photolithography, if significant control of uniformity and defects can be achieved. Herein we demonstrate a new evaporative co-assembly method for highly-uniform inverse opal thin films that involves the self-assembly of polymer colloids in(More)
