Material for substrate mounting optical circuit-electrical circuit mixedly and substrate mounting optical circuit-electrical circuit mixedly

Abstract

A material for an optical circuit-electrical circuit mixedly mounting substrate comprises a light permeable resin layer, and an optical circuit forming layer that is made of a light permeable resin of which refractive index increases (or decreases) when irradiated with an activating energy beam and is disposed adjacent to the light permeable resin layer, wherein a refractive index of a portion of the optical circuit forming layer is higher (or lower) than that of the light permeable resin layer when the material for the optical circuit-electrical circuit mixedly mounting substrate is irradiated with an activating energy beam so that said portion is irradiated.

1 . A material for an optical circuit-electrical circuit mixedly mounting substrate comprising: 
 a light permeable resin layer, and    an optical circuit forming layer that is made of a light permeable resin of which refractive index decreases when irradiated with an activating energy beam and is disposed adjacent to the light permeable resin layer,    wherein when the material for the optical circuit-electrical circuit mixedly mounting substrate with an activating energy beam is irradiated so as to irradiate a portion of the optical circuit forming layer, the refractive index of said portion is higher than that of the remaining non-irradiated portion of the optical circuit forming layer. The material for the optical circuit-electrical circuit mixedly mounting substrate is again a composite material as in the above wherein at least two layers are stacked, namely a laminate structure.    
     
     
         2 . The material for the optical circuit-electrical circuit mixedly mounting substrate according to  claim 1  further comprising a second light permeable resin layer, 
 wherein the optical circuit forming layer is disposed between the light permeable resin layer and the second light permeable resin layer, and    when the activating energy beam is applied to the material for the optical circuit-electrical circuit mixedly mounting substrate so that a portion of the optical circuit forming layer is irradiated with the activating energy beam, a refractive index of the rest of the optical circuit forming layer is higher than that of the second light permeable resin layer.    
     
     
         3 . A material for an optical circuit-electrical circuit mixedly mounting substrate comprising: 
 a metal layer, and    an optical circuit forming layer that is made of a light permeable resin of which refractive index decreases when irradiated with an activating energy beam and is disposed adjacently to the metal layer,    wherein when the material for the optical circuit-electrical circuit mixedly mounting substrate is irradiated with the activating energy beam on a portion of the optical circuit forming layer, the refractive index of said portion of the optical circuit forming layer irradiated with the activating energy beam is lower than that of the rest of the optical circuit forming layer that is not irradiated with the activating energy beam.    
     
     
         4 . The material for the optical circuit-electrical circuit mixedly mounting substrate according to  claim 3  further comprising a light permeable resin layer, 
 wherein the optical circuit forming layer is disposed between the metal layer and the light permeable resin layer, and    when the activating energy beam is applied to the material for the optical circuit-electrical circuit mixedly mounting substrate so that a portion of the optical circuit forming layer is irradiated with the activating energy beam, the refractive index of the rest of the optical circuit forming layer that has not been irradiated with the activating energy is higher than that of the light permeable resin layer.
