The invention relates to a modular 
transistor outline can with internal components. In one example configuration, an optical 
package includes a substrate that supports a 
laser. The 
laser is configured for electrical communication with circuitry disposed on the substrate, and the 
laser is arranged to emit an optical 
signal along a first path. The optical 
package also includes a 
beam steering device supported by the substrate and arranged so as to receive the optical 
signal from the laser along the first path. The 
beam steering device is configured such that the optical 
signal is output from the 
beam steering device along a second path. A group of electronic leads is provided that electronically communicates with the circuitry on the substrate. In this example, the group includes a set of modulation leads in electrical communication with the laser, and a set of bias leads in electrical communication with the laser. The set of bias leads is electrically isolated from the set of modulation leads.
