In some embodiments, apparatus and systems, as well as methods, may operate to select from multiple optical detectors and/or multiple detector amplifiers to form combinations of detectors and amplifiers as part of an optical detection system. The selection may be based on minimizing noise equivalent power (NEP) of the optical detector or a combination of an optical detector and a detector amplifier over a desired temperature range. Additional apparatus, systems, and methods are disclosed.

Detector, preamplifier selection apparatus, systems, and methods

Optical detection apparatus () comprising an optical detector (), a detector amplifier (), and switching means, e.g., a multiplexer (), for dynamically selecting at least one of the optical detector or the detector amplifier by switching from among at least two alternative optical detectors and/or at least two detector amplifiers such as to minimize noise equivalent power (NEP) of a selected detector or combination of detector and amplifier under given operating conditions.
