1. An optical sensor system for measuring a property of a target matter, said system comprising:
a light source comprising at least,
an interposer having first and second opposing sides and defining at least one alignment aperture extending from said first opposing side to said second opposing side;
at least one fiber disposed in said at least one alignment aperture, said at least one fiber having a first optical axis;
at least one light generating component mounted to said second opposing side and having a second optical axis coincident with said first optical axis, said light generating component configured to emit light, at least a portion of which is coupled with said at least one fiber as coupled light,
a feedback component configured to provide feedback to said at least one light generating component such that said at least one light generating component maintains constant optical power; and
at least one optical sensor optically coupled to said at least one fiber and configured to direct at least a portion of said coupled light at a target matter and transmit a sensor signal back on said at least one fiber, and
at least one optical sensor receiving component configured to receive at least a portion of said sensor signal to measure a property of said target matter.
