Abstract:
1. An optical module, comprising: a planar lightwave circuit including a waveguide-type optical functional circuit formed on a substrate, the waveguide-type optical functional circuit having a waveguide region where only an optical waveguide is formed in contact with a side, wherein an end face of the optical waveguide is formed in contact with the side, the end face being an emission end face where output light is emitted from the optical functional circuit, or an entrance end face where input light is entered to the optical functional circuit; a fixing mount employed to hold the planar lightwave circuit only in a portion where the waveguide region is located; and an auxiliary mount employed to hold the planar lightwave circuit in contact with a side that is opposite the side in contact with the end face, wherein the planar lightwave circuit and the auxiliary mount are fixed together by employing an elastic adhesive or an elastic structure that has lower elasticity than that of an adhesive or a bonding material that rigidly fixes the planar lightwave circuit to the fixing mount.
