Abstract :
A high-power RWG pump laser free of kink and beam steering is proposed and demonstrated. It utilises the ion implanted region formed in channel as a lateral mode selective absorber for the purpose of suppressing the higher-order mode excitation. The fabricated 0.98 μm pump lasers exhibit high-power operation up to 250 mW without any kink and beam steering
