INTRODUCTION

SEMICONDUCTOR OPTICAL AMPLIFIER

Fabry-Perot Amplifier Traveling wave amplifier

To make a traveling wave Semiconductor

Optical Amplifier,reflectivity must be

reduced.

Three approaches are commonly used:

Anti-reflection coating

Tilted Active Region

Use of transparent window regions
