A lattice matched multiple quantum well (MQW) structure was used to fabricate 10-channel electro-absorption (EA) modulator arrays. The method was based on using gray mask lithography and a low-energy arsenic ion-implantation induced disordering (IIID). The EA modulators were characterized through photocurrent measurements using end-fire-coupling technique. The polarization sensitivity of the devices was determined using the degree of intermixing on the group V sublattices.
