Abstract: The present disclosure relates to optical systems and methods for their manufacture. An example system includes a first substrate that has at least one bridge structure. The bridge structure has a first surface with one or more light-emitter devices disposed on it. The system also includes a second substrate that has a mounting surface that defines a reference plane. The second substrate includes a structure and an optical spacer on the mounting surface. The first and second substrates are coupled together such that the first surface of the first substrate faces the second substrate at an angle with respect to the reference plane. The system also includes at least one spacer coupled to the mounting surface. The at least one spacer is in physical contact with the one or more light-emitter devices.
