Abstract:
1. A planar waveguide comprising an NaCa-boroaluminosilicate glass material having a composition of: approximately 56 mole % to approximately 60 mole % SiO 2 ; approximately 4 mole % to approximately 6 mole % Al 2 O 3 ; approximately 16% to approximately 18% B 2 O 3 mole %; approximately 10 mole % to approximately 15 mole % Na 2 O; approximately 9 mole % to approximately 10 mole % CaO; and 0.5 mole % PbS, the waveguide further comprising: a cladding layer having a first ionic component and quantum dots; and an active layer having quantum dots and a second ionic component, the second ionic component being present within the active layer at a greater concentration than in the cladding layer.
