Claim 0:
1. An optical transducer for use with an endoscope, the optical transducer comprising:
an optical element;
an optical fiber optically coupled with the optical element; and
a ferrule comprising:
a semiconductor substrate including a first principal surface and a second principal surface opposite to the first principal surface, the semiconductor substrate having an insertion hole penetrating the semiconductor substrate from the first principal surface to the second principal surface, the optical fiber is disposed in the insertion hole, and
a glass substrate including a third principal surface and a fourth principal surface opposite to the third principal surface, and the third principal surface is bonded with the second principal surface, the optical element is mounted on the fourth principal surface,

wherein the semiconductor substrate includes a trench having an opening in a side surface of the semiconductor substrate, the trench extending from the opening to the insertion hole, and
at least a portion of a circumferential surface of the optical fiber is exposed through the opening.
