Abstract
An optical fiber module of the invention is an optical fiber module easily fabricated and excellent in the characteristics of enduring high intensity light, for example. The connection end face of an optical fiber array as an optical component is faced to the connection end face of a planar lightwave circuit component. An optical fiber array is also disposed on the connection end face of the planar lightwave circuit component opposite to the optical fiber array. The corresponding connection end faces are connected to each other with an adhesive. A no adhesive filled part where the adhesive is not applied in the light transmitting area is disposed in at least one of bonding parts thereof.
Claims24
An optical fiber module comprising:
- at least one bonding part connecting optical components with an adhesive, the optical components having connection end faces faced to each other,
- wherein at least one of the bonding parts has a no adhesive filled part where the adhesive is not applied in a light transmitting area.
An optical fiber array comprising:
- a guide substrate having a plurality of optical fiber guide grooves arranged at a pitch nearly twice a diameter of an optical fiber;
- and
- optical fibers inserted into the optical fiber guide grooves in the guide substrate, wherein a total number of the optical fiber grooves is 20 grooves or greater, and a thickness of the guide substrate is 1.10 mm or greater.
The optical fiber array according to claim 14, wherein the thickness of the guide substrate is thickened continuously or step by step as the total number of the optical fiber guide grooves is increased corresponding to the total number of the optical fiber guide grooves.
An optical fiber array comprising:
