Abstract

See full text

A semiconductor laser device comprises a stem serving as a base; a laser diode LD submount having surface electrodes arranged thereon and joined to the surface of the stem; an LD chip joined to the surface electrode and connected with the surface electrode; and leads fixed in through holes formed in the stem by means of sealing parts and electrically connected to the surface electrodes via embedded layers in via holes formed in the LD submount, wherein grooves are formed in portions of the sealing parts or in portions of the LD submount around the connections between the leads and the embedded layers, to obtain a good modulated light waveform.
