Abstract
Mesoporous silicon optical filters can be used to filter light in the near infrared, mid infrared and/or far infrared spectral ranges. The special advantages of mesoporous filters in cold temperature applications include improved mechanical stability, absence of delamination problems, manufacturability, and transparency of the mesoporous silicon material throughout a wide spectral range. Techniques are disclosed for enhancing the transparency range and environmental and mechanical stabilities of the mesoporous silicon filters.
