1. A glass sealing sheet comprising:
- a glass core layer having a first side and a second side;
a first cladding layer bonded to the first side of the glass core layer; and
a second cladding layer bonded to the second side of the glass core layer;
wherein;
the first cladding layer has a first coefficient of thermal expansion and comprises a glass composition that is absorbing of radiation over at least a portion of an emission wavelength range;
the second cladding layer has a second coefficient of thermal expansion and comprises a glass composition that is different from the glass composition of the first cladding layer; and
a differential between the first coefficient of thermal expansion and the second coefficient of thermal expansion ranges from about 0×

11. A method of manufacturing a glass sealing sheet, the method comprising:
-
melting a core glass composition to form a molten core glass composition; melting a first cladding glass composition to form a molten first cladding glass composition, the first cladding glass composition being absorbing of radiation over at least a portion of an emission wavelength range; melting a second cladding glass composition to form a molten second cladding glass composition that is different from the first cladding glass composition; flowing the molten core glass composition, the molten first cladding glass composition, and the molten second cladding glass composition such that they converge and form a composite flow; and drawing the composite flow into a glass sealing sheet comprising; a glass core layer comprising the core glass composition and having a first side and a second side; a first cladding layer comprising the first cladding glass composition and a first coefficient of thermal expansion and bonded to the first side of the glass core layer; and a second cladding layer comprising the second cladding glass composition and a second coefficient of thermal expansion and bonded to the second side of the glass core layer; wherein a differential between the first coefficient of thermal expansion and the second coefficient of thermal expansion ranges from about 0×
