PASSIVE TEMPERATURE-INSENSITIVE FABRY-PEROT ETALONS

摘要

PASSIVE TEMPERATURE-INSENSITIVE FABRY-PEROT ETALONS Both the fiber and the bulk Fabry-Perot etalons can be made temperature insensitive by the addition of a compensator element. This element adjusts the optical length of the air-gap in the etalon cavity so as to compensate for any changes in the optical length of the fiber or the etalon slab due to ambient temperature changes.
