Claim:
1. An apparatus comprising: a first laser having a first core of a first diameter, and a first cladding layer surrounding said first core; a second laser having a second core of a second diameter, and a second cladding layer surrounding said second core; a geometric isolator connected between said first laser and said second laser, wherein said geometric isolator includes a third core of a third diameter, and a third cladding layer surrounding said third core, wherein said third diameter of said third core is significantly larger than said first diameter of said first core or said second diameter of said second core in order to generate a geometric mismatch between said first core and said second core for providing a geometric isolation between said first laser and said second laser; and a cladding mode stripper coupled on a first end to the first laser and coupled on a second end to the geometric isolator.
