  • Coefficient of thermal expansion (CTE) matched transistor outline (TO) header
    Patent number: 10050410
    Abstract: A transistor outline (TO) package may include a TO cap. The TO package may include a TO header. The TO header may include a header stem of a first material and a first coefficient of thermal expansion (CTE) value. The TO header may include a header base of a second material and a second CTE value. The first material and the second material may be different. The first CTE value and the second CTE value may be different. The first CTE value and the second CTE value may be within a threshold percentage of each other.
    Type: Grant

  • Fiber coupled laser source pump with wavelength division multiplexer
    Patent number: 9935425
    Abstract: A pump laser package may include an input fiber to send signal light on a first optical path. A first lens may be arranged on the first optical path. The pump laser package may include a source to send pump light on a second optical path. A second lens and a negative lens may be arranged on the second optical path. The first lens and the negative lens may be arranged to create a virtual image associated with the pump light. The pump laser package may include an output fiber on a third optical path. The first lens may be arranged on the third optical path. The pump laser package may include a combiner to receive the signal light on the first optical path, receive the pump light on the second optical path, and send the signal light and the pump light on the third optical path.
